Real Salt Lake: Perennial Model Buster?

If you take a look back at 2013's expected goal differentials, probably the biggest outlier was MLS Cup runner up Real Salt Lake. Expected to score 0.08 fewer goals per game than its opponents, RSL actually scored 0.47 more goals than its opponents. That translates to a discrepancy of about 19 unexplained goals for the whole season. This year, RSL finds itself second in the Western Conference with a goal differential of a massive 0.80. However, like last year, the expected goal differential is lagging irritatingly behind at --0.77. There are two extreme explanations for RSL's discrepancy in observed versus expected performance, and while the truth probably lies in the middle, I think it's valuable to start the discussion at the extremes and move in from there.

It could be that RSL plays a style and has the personnel to fool my expected goal differential statistic. Or, it could be that RSL is one lucky son of a bitch. Or XI lucky sons of bitches. Whatever.

Here are some ways that a team could fool expected goal differential:

1. It could have the best fucking goalkeeper in the league.
2. It could have players that simply finish better than the league average clip in each defined shot type.
3. It could have defenders that make shots harder than they appear to be in each defined shot type--perhaps by forcing attackers onto their weak feet, or punching attackers in the balls whilst winding up.
4. That's about it.

We know are pretty sure that RSL does indeed have the best goalkeeper in the league, and Will and I estimated Nick Rimando's value at anywhere between about six and eight goals above average* during the 2013 season. That makes up a sizable chunk of the discrepancy, but still leaves at least half unaccounted for.

The finishing  ability conversation is still a controversial one, but that's where we're likely to see the rest of the difference. RSL scored 56 goals (off their own bodies rather than those of their opponents), but were only expected to score about 44. That 12-goal difference can be conveniently explained by their five top scorers--Alvaro Saborio, Javier Morales, Ned Grabavoy, Olmes Garcia, and Robbie Findley--who scored 36 goals between them while taking shots valued at 25.8 goals. (see: Individual Expected Goals, and yes it's biased to look at just the top five goal scorers, but read on.)

Here's the catch, though. Using the sample of 28 players that recorded at least 50 shots last season and at least 5 shots this season, the correlation coefficient for the goals above expectation statistic is --0.43. It's negative. Basically, players that were good last year have been bad this year, and players that were bad last year have been good this year. That comes with some caveats--and if the correlation stays negative then that is a topic fit for another whole series of posts--but for our purposes here it suggests that finishing isn't stable, and thus finishing isn't really a reliable skill. The fact that RSL players have finished well for the last 14 months means very little for how they will finish in the future.

Since I said there was a third way to fool expected goal differential--defense. I should point out that once we account for Rimando, RSL's defense allowed about as many goals as expected. Thus the primary culprits of RSL's ability to outperform expected goal differential have been Nick Rimando and its top five scorers. So now we can move on to the explanation on the other extreme, luck.

RSL has been largely lucky, using the following definition of lucky: Scoring goals they can't hope to score again. A common argument I might expect is that no team could be this "lucky" for this long. If you're a baseball fan, I urge you to read my piece on Matt Cain, but if not, here's the point. 19 teams have played soccer in MLS the past two seasons. The probability that at least one of them gets lucky for 1.2 seasons worth of games is actually quite high. RSL very well may be that team--on offense, anyway.

Unless RSL's top scorers are all the outliers--which is not impossible, but unlikely--then RSL is likely in for a rude awakening, and a dogfight for a playoff spot.

*Will's GSAR statistic is actually Goals Saved Above Replacement, so I had to calibrate.

How it Happened: Week One

Hello friends. This is the first in what will hopefully be a weekly feature here at ASA by yours truly. First, the background: Not being a fan of any particular MLS team is hard. It's hard to follow an entire league of 19 teams. Seven or eight games a week are difficult to catch up on, even when they aren't all played at the same time. Previously, I've watched highlights and 'condensed games' to try to pick up which teams and players were playing well, but it just doesn't work. The only way to really learn a team's strengths, weaknesses and tendencies is by watching every minute of every game they play. There's no way I can do that with every team in MLS while still working a full-time job. Sorry.

My solution is this: I plan on committing to watching a full 90 minutes of three games per week. This gives me six teams that I'll feel that I truly know (at least for that week), and should certainly teach me a heckuva lot more than just if I just watched their highlight packages. Since this here is an analytical and statistic-focused blog, I'll break down each of the three games by one particular stat or Opta chalkboard image that I think told the story of the game for each team. Think this idea is idiotic? Love it? Please, let me know: feedback is always appreciated. But leave my mom out of this.

DC United vs. Columbus Crew

Stat that told the story for Columbus: 58% of successful passes in attacking half for the fullbacks

The above image is all of the completed passes for Crew fullbacks Waylon Francis and Josh Williams on Saturday. These two players are clearly defenders who aren't afraid to get forward, but the startling frequency with which they were able to get up the field against DC had to have alarm bells ringing for United fans. For folks who prefer numbers to images, here you are: 49 of the 85 passes that Francis and Williams completed (58%) were in the attacking half. That's a pretty solid attacking contribution from two guys who are listed along the back line.

This was made possible for Columbus by a couple of adjustments made by new coach Gregg Berhalter. Centerbacks Michael Parkhurst and Giancarlo Gonzalez split reallllly wide when in possession, allowing both fullbacks to get forward. This was made possible by holding midfielder Wil Trapp, who sat very deep to cover the gap between centerbacks. It's only one game, but it certainly looked like a good strategy in week one for Columbus.

Stat that told the story for DC: 1 attacking player's pass into the penalty area

Really, the above image for Columbus tells a lot of the story for DC, as well: they got hammered because the Crew got the ball wide and stretched DC's shape like a bad hamstring. With a team full of new faces who clearly haven't learned to play with one another yet, the defense was abused by all the space Crew players were able to find. But I can't use the same stat for both teams, so here's what I got for United: one. One successful pass from any of the three players nominally deployed in attack (Eddie Johnson, Fabian Espindola, Luis Silva) that ended in the penalty box.

Seriously: take a look at the Opta Chalkboard above. I get that it's hard to complete passes in the 18, but for the three guys who are tasked with creating chances, there needs to be more than one completed pass that ends up there. Oh, and that one completed pass? It came from a free kick, and ended with a flick-on by Davy Arnaud that didn't even turn into a shot. There was a lot wrong with DC in 2013 and a lot wrong with DC last weekend, but if the new faces of Johnson and Espindola were expected to cure all attacking ills....Ben Olsen may be in for a rude awakening.

Portland Timbers vs. Philadelphia Union

Stat that told the story for Portland: 20 crosses in the second hour of the game

The Timbers came out for the season opener and were dealt a dose of their own medicine from the new-look Philadelphia Union. Playing in a 4-3-3, the Union clogged the center of the field, put a lot of pressure on Portland and really made it difficult for the home team to get into their possession game. But as any good team does, the Timbers made adjustments. After being credited with just two crosses from open play in the games first 35 minutes, Portland emphasized wide play with Michael Harrington getting forward and Darlington Nagbe flaring out wide. After the 35th minute, Opta credited Portland with 20 crosses from open play. Some of this was due to bombing the ball forward as they sought an equalizer late, but recording 10 times as many crosses was certainly the product of an adjustment made by the Timbers.

Stat that told the story for Philadelphia: 12 midfield interceptions & recoveries to start the game

As I said above, the Union started the game very strong, with their midfield really clogging up Portland's attempts to possess the ball. The midfield three of Maurice Edu, Brian Carroll and Vincent Nogueira seemed to be replicating some of what made Portland so successful in 2013: clogging the middle of the field and winning a majority of loose balls. Opta credits those three with 12 combined interceptions and recoveries in the game's first 22 minutes. However, as also noted above, Portland adjusted to the Union's set-up and began to emphasize wide play. The Union didn't really adjust to the adjustment, as the Timbers clearly became more and more comfortable as the game went on. After those 12 interceptions/recoveries in the first 22 minutes, Edu, Carroll and Nogueria only recorded seven more the rest of the game.

LA Galaxy vs. Real Salt Lake

Stat that told the story for LA: 2.39 expected goals; 0 actual goals

If you're at this site, chances are you know the concept behind expected goals. If not, scroll down a ways and read up. Anyway, look at the above image: that's not a map of shots that typically leads to a shutout. According to the numbers run by ASA's own Harrison Crow, a league average team would've finished 2.39 goals from those shots. They finished zero. If you aren't into the stats and would prefer the English commentator's version: Robbie Keane missed some sitters, Landon Donovan was unlucky not to finish any of his half-chances, and Juninho and Marcelo Sarvas combined for some speculative efforts that nearly bulged the ol' onion bag. Oh, and Nick Rimando had a magisterial day in net to keep his clean sheet.

Stat that told the story for RSL: Joao Plata's complete game

I'm cheating a little here because that's not a real stat, but any time there's a 1-0 game, it's tough to leave out any conversation about the lone goal scorer. In this case, that's the diminutive Ecuadorian, Joao Plata. Plata debuted for Toronto FC three seasons ago, and it seems like he's been around for a lot longer than your average 22-year-old. But it's true. Plata is only 22, and if Saturday night is any indication, he could be in for his best season in MLS yet. Not only was Plata's finish on the game's only goal very cool, he was consistently playing with a lot more tactical awareness than I've seen out of him in the past. Whether it was setting up Alvaro Saborio for golden chances or making intelligent runs to stretch the defense and open up space for Javier Morales, Plata had a very, very good game against LA.

Season Preview: Real Salt Lake

The optimist looks at Real Salt Lake’s 2013 season and praises the club for making the MLS Cup Finals. The pessimist complains that they lost the MLS Cup Finals in penalty kicks despite holding a lead with 15 minutes remaining, facing a goalkeeper who seemed like his joints had frozen solid. The optimist praises the club’s performance in the U.S. Open Cup, lauding their run to the finals. The pessimist complains that they lost in the finals against DC United, a dreadful team. The optimist praises the team for finishing with a 16-10-8 record and a +16 goal differential in the regular season. The pessimist complains that they failed to win the Supporters Shield (again!) by 3 points. For Real Salt Lake in 2013, perception was everything. 

2013 Finish: 16-10-8, 56 points; 57 GF, 41 GA. Second place in Western Conference. Lost in MLS Cup Finals.

Roster Churn: RSL returns 90.5% of its minutes played in 2013 (1st in all of MLS).

Know When to Hold ‘Em

In early 2013, Real Salt Lake owner Dell Loy Hanson made the decision not to extend Jason Kreis’s contract, gambling that Kreis’s stock would come down and he would be able to nab the coach at a bargain price. After all, the club had just lost Will Johnson, Jamison Olave, Fabian Espindola, and Jonny Steele in an offseason filled with cost-cutting moves. 2013 seemed likely to be a rebuilding year. Twelve months and two cup finals later, Jason Kreis is preparing for the 2015 debut of New York City FC, leaving Jeff Cassar, promoted from assistant coach, to lead Real Salt Lake. Cassar, with the team since 2007, is a safe choice, but even with all 11 starters returning, he may find it difficult to replicate the kind of success that RSL achieved under Jason Kreis.

In Good Hands

Nick Rimando returns to man the RSL nets for the 8^th consecutive season. There’s nothing much that can be said about Rimando that you probably don’t already know. A 14-year veteran of the league, Rimando has ascended to third in command of the United States net. Remarkably, Rimando has a 10-0-0 record with the U.S. team, and is already tied for 5^th all-time on the goalkeeper victory list with Brad Guzan.

Rimando’s national team opportunities have come as a result of stellar club play. Last season, he finished 2^nd to Donovan Ricketts in Goalkeeper of the Year award voting, and was probably unlucky to do so. Rimando really is the total package: His reflexes and shot-stopping ability are legendary, and while it may not surprise you that Rimando finished 4^th in pass completion percentage, the diminutive Rimando is also an excellent commander of his penalty area. In 2014, Rimando finished 4^th in MLS in catches per 90 with 2.63. This paragraph is far too long for one that could have been summed up simply with "Real Salt Lake is in good hands with Nick Rimando."

Continuity in the Back

With Chris Wingert, Nat Borchers, Chris Schuler, and Tony Beltran patrolling in front of him, Nick Rimando, too, will be in good hands. In the playoffs, Borchers and Schuler showed the potential to become one of the best pairings in the league. Though that is contingent on whether Schuler can remain healthy. In both the 2012 and 2013 seasons, Schuler was sidelined for multiple months with a foot injury. It was evident just how much Salt Lake missed Schuler last season when he was injured: with Schuler on the field last season, RSL conceded only 0.94 goals per 90, without him, they conceded 1.45 goals per 90. Yes, the sample size is small, and no, these numbers do not take into account opponent and location of the game. Still, Schuler’s contributions to defense were evident when 20-year old Carlos Salcedo was forced to step in. Nat Borchers provides much more certainty. In his 9-year Major League Soccer career (he spent two years with Odd Grenland in Norway), Borchers has averaged more than 28 starts per season.

The Best Defense…

However, for all they do defensively, it may be their contributions to the attack that makes the RSL backline so valuable. Nat Borchers is one of the calmest defensive distributers in the league. Last season he had the 3^rd best pass completion rate in the league, behind only Osvaldo Alonso and George John. This may be because Real Salt Lake puts a premium on possession and building the attack from the back, which sees Beckerman and the rest of the midfielders providing outlet options constantly. The team led MLS last season in possession percentage, pass success percentage, and percentage of passes that were under 25 yards. After all, Kwame Watson-Siriboe finished with a 93% passing rate (in but a mere handful of games), and Carlos Salcedo and Schuler both finished above 80%.

Wingert and Beltran involve themselves in the attack as well, though not always in the traditional, bomb-down-the-flanks-and-send-in-a-cross manner. When Real Salt Lake is in possession, the two outside backs (and Beltran especially) inhabit an advanced position on the field, where they can combine effectively with Gil, Grabavoy, Morales, and Saborio. Beltran is the more threatening of the two outside backs, finishing last season 5^th in the league in key passes among defenders with 25.

Owning the Ball

The midfield will look awfully familiar for RSL fans this season as well, and why shouldn’t it? No midfield quartet in MLS can control the pace of the game like Kyle Beckerman, Ned Grabavoy, Luis Gil, and Javier Morales. Beckerman provides the transition from defense to attack, from left to right. He does it often, and he does it well. The only midfielder with more passes than Beckerman last season was Marcelo Sarvas, who had 3 more passes than Beckerman, though the Galaxy midfielder did it in 610 more minutes. Beckerman was the runaway leader in passes per game with 69.7, nearly 10 more than number two on the list. And though better known for his grit and tactical nous, Beckerman also manages to throw in no-look assists from time to time, just for fun (and to [almost] win MLS Cup).

Number two on that list of passes per game in MLS last year? None other than Javier Morales. Though he always has a target on his back, the 34-year-old Argentine playmaker often drifts wide and deep to ensure that he sees enough of the ball. And when he gets the ball, RSL benefits. Last season, Morales finished (per game) in the top 10 in fouls suffered (1^st), key passes (2^nd), successful through balls (4^th), and successful crosses (6^th).

These numbers are gaudy enough, but numbers like that are often indicative of a high-risk style of play, sending in large numbers of passes and crosses to in the hopes that a few of them will lead to dangerous scoring opportunities. And while he does send in a lot of passes (Morales has attempted [2,327] and completed [1,857] more passes in the opponent's half than any other MLS player over the last two years), what sets Morales apart from his peers is his effectiveness. While the average pass completion percentage of the rest of the top ten “key passers” (all attack-minded players) in 2013 was 76.6%, Morales’s was a hearty 83.1%. This number is inflated a bit both because he plays on such a talented, possession-oriented team and because he receives the ball farther from goal than, say, Thierry Henry or Robbie Keane, both of which lead to more safe ball touches. But even with these advantages, Morales should be regarded as one of the most talented players in the league, one who was unfortunate not to have been included in the MVP race last season.

The Other Guys

The rest of the midfield will be rounded out by two of the most underrated players in the league. Gil gets more publicity than Grabavoy. He did when he signed with Major League Soccer amid rumors of pursuit by clubs like Arsenal, and he does as a 20-year-old who has caught the eye of Jurgen Klinsmann. Gil deserves his plaudits, of course. After all, how many MLS players have played in 84 games before their 20^th birthday? (By my count, just Freddy Adu and Eddie Gaven, though others, like Diego Fagundez, should get there).

But how many times have you heard Ned Grabavoy referenced recently? If you listen to the media or fans, probably not very many, but if you’re taking note of the play-by-play man on an RSL broadcast, you probably hear it quite often. Grabavoy is everywhere on the field: relentlessly pressuring the ball (he finished 14^th last season in tackles per game among midfielders), and then quickly and efficiently--far more than he gets credit for (86% pass completion rate, 4^th best in MLS)--distributing it. Remarkably, despite all of Grabavoy’s defensive grit, he finished tied for 6^th among MLS midfielders in fouls suffered with 63 (9^th in fouls per game with 2.0), and committed only 37 himself. If that’s not enough, he pitched in with 5 goals on only 29 shots, intelligently taking 20 shots inside the box versus only 9 outside.

The Finishers

Up top, Salt Lake will deploy their preferred pair of Alvaro Saborio and Robbie Findley. Saborio may be the most indispensable member on the RSL squad. He has scored at least 11 goals in each of the four seasons he has been in the league. Last season, due to injuries and international call-ups, he only managed 15 starts, yet still racked up 12 goals. His .80 goals per 90 minutes led the league.

Findley will provide support for Saborio. He may not have the greatest skill on the ball, but his pace down the channels draws defenders out of position and opens up space for Saborio and streaking midfielders. However, if Findley gets off to a slow start, he’ll have to watch his back. Last season, the trio of Olmes Garcia, Joao Plata, and Devon Sandoval, three very different types of forwards, all showed promise, and will be looking for even more playing time this season.

The Prediction

This preview has featured incessant, nearly sycophantic levels of praise for RSL players, but years of success despite shuttling players in and out of Utah to stay under the salary cap suggests that maybe it’s the system just as much as it is the players. After all, when Sebastian Velazquez filled in for Luis Gil, he looked great. Same for Yordany Alvarez for Ned Grabavoy. Joao Plata, Robbie Findley. Sandoval, Saborio. How much of the success of RSL was because of the system? How much of the system was based on Kreis’s presence?

American Soccer Analysis readers seem to think that the team will not have quite the same success this year. They have projected RSL to finish 4^th in the Western Conference this season, with 20.69% of voters placing them there. Although very few people think that they will miss the playoffs entirely, with only 13.05% of voters placing them in spots six through nine.

New England Revolution acquires Juan Agudelo: What does that mean?

First things first before I make fun of the Revolution (and I will).  Their defense has been---excluding the New York outlier---borderline elite this season. That's possibly one of the few reasons they're still afloat and maybe the only reason to watch them (sorry, Lee Nguyen).

Tempo-free soccer has the Revs ranked 6th in dAG (defensive attempts on goals), which is how many times an opposing team has made any attempt at their goal. Add to that that we have them ranked 2nd (6.2%) in Opposing Finishing%, which is how often a team's opponents successfully convert attempts into actual goals. They're better than every team outside of Montreal in that category.

This has all culminated in only 6 goals allowed in 9 games. Something that would be overlooked if it wasn't for their horrible attack and the need for at least some positive mention.

But now the Revs have added the young (former starlett?) Juan Agudelo, someone who saw time with the US National team only 6 months ago in Russia and didn't look awful by any stretch. To be fair, he's someone that has actually come out looking very strong for Chivas earlier this season, but he's been hampered the last few weeks with hamstring issues.

It was thought that he had mended a brewing off-season situation between himself and Chivas USA head coach, El Chelis. But of late, Chelis has given a lot of credit to his now former striker. He told MLSSoccer:

"I didn’t know what I had in Agudelo, but by having him, what I asked for doesn’t matter because Agudelo is a model. He is the natural on this team. He’s a player that has many technical qualities. He’s very involved in working to improve others."

And now he's shipped off to the greater Boston area and we are with out the full detail of the acquisition being yet to be vented  in exchange the Goats received allocation money. The spice of life and magic dust that no one talks about and everyone wants. Of course for us this isn't about the details at this point.

What Juan Agudelo will bring is spectacular things and then all together frustrating things. He averages about 16 shots on goal per 1500 minutes, a number he has yet to reach in either of his stops in Chivas or New York. A team averages a goal on 9.4% of its attempts this season, and 26.9% of its shots on goal. Using that, there's a possibility that he adds a few additional goals to the line-up. Assuming he is just average at finishing.

That said Agudelo has beat the average ratio over his 3,000 minutes, scoring 11 goals in 36 shots on goal (30.6%). Scoring goals is a skill, and though we don't know how much is luck vs. his ability, I think it's very possible that he will continue to beat the league average conversion rates.

Looking at Chris Wondolowski, Kenny Cooper and Álvaro Saborío--the top 3 scorers for 2012--they all combined to beat the league average by scoring a goal on 43.9% of their shots on target. So, we can safely attribute scoring goals on shots on target as being a skill, the only problem is trying to account for luck. That's a little difficult at this stage, and so for now, we'll just mention it.

But assuming that Agudelo is consistent and continues scoring at a high rate and matches 1500 minutes. I have him for about 6 goals this season. Right now considering their goal conversion and their already abysmal offense, the Revs are on pace for 36 goals total to end the season. Considering their ability to suppress their opponent's talent and ability to score goals I have them for 26 goals allowed, assuming they continue their defensive supremacy.

Using SoccerMetricsPythagorean this comes out at about 51 points... given the asinine goal difference. Add in the additional 6 goals that Juan Agudelo brings and that brings them to a total of 56. Basically almost a full point for each goal.

Now, I'm not about to say that the Revolution have a shot at 60 points, not in your life. But in the last 3 years the only teams to have a plus goal differential AND not make the playoffs were 2011 Chicago Fire and the 2010 Kansas City Wizards. Considering a team-wide return to a league-average ability to score goals AND adding Juan Agudelo, it's very possible that New England just moved themselves within striking distance for the 4th or 5th spot in the East.

Columbus and Philly, beware.
