Dugout Central: Jensen: Reyes and Rollins are NL’s Most Overrated Players

This Jensen isn’t afraid of flying...by the seat of his pants.

Determining who the most overrated players are is inherently difficult – and subjective. Whose ability to rate players are we evaluating? Fans, writers, hardcore fans, players, fantasy geeks? Today I’m going to look at writers in the BBWAA– since their voting on MVP provides direct and clean evidence as to who they feel are the cream of the crop.

Jose Reyes

MVP finishes: ’05-‘07

2007 – 16th
2006 – 7th
2005 – 30th

Reyes is young, flashy and plays in New York, so perhaps that’s part of the reason he’s overrated. His OPS+ the past three years has been 103, 115 and 81, and his career OPS+ is 97. In 2005 he finished 30th (granted that’s not high, but was he the 30th best player in the league?) in the NL MVP voting despite being a significantly below average offensive player and posting an OPS of .686. Like Rollins, Reyes is essentially an average offensive player when discounting the effect of steals. Also like Rollins, he’s a fantasy stud – and someone I’d want on my team. But he’s not in the upper echelon of players.

I have not read the #### article, nor do I plan to. However, when you rate a shortstop who is a prolific basestealer with OPS+, you are making a mistake. A lot of Jose Reyes's value comes from his talent in the field, his position, and his abilities to run the bases extremely well. OPS+ captures none of that.
   4. Rich Rifkin Posted: April 05, 2008 at 02:34 AM (#2731473)
Equivalent Average, like OPS+, misses the defensive value, but it captures the base-stealing. To see a bit of the difference, note these two OPS+ numbers from 2007:

Jose Reyes - 103
Pat Burrell - 127

But then compare their EqA's from 2007:

Jose Reyes - .277
Pat Burrell - .304

Burrell is still better, but it's closer.

Some don't like WARP numbers (because the way defensive value is measured). That said, look again at those two by WARP3 in 2007, which accounts for defense, offense and base running:

Jose Reyes - 10.3
Pat Burrell - 5.4

Maybe these numbers are off. But they are a much better approximation of the value of Burrell and Reyes in 2007 than OPS+ is.

Exactly right. That is a ridiculous article. No attempt is ever made to look at defensive metrics. I don't think you can begin to talk about whether a shortstop is overrated or not without including an evaluation of their defense.

Reyes's 30th place finish was a result of one 10th place vote. It's perfectly cromulent to throw a 10th place bone to the guy who led the league in triples and stolen bases. Lets not make too much of that shall we? Scott Eyre and Jorge Cantu also got a 10th.

what's the pOPS+ of NL SS? by that standard, Rollins and Reyes would come out looking a lot better than just OPS+, and it'd be more accurate given that it's their position. likewise, both bringing very good defense to the position, it's not like the Mets and Phillies are running out someone who can't really play the position but has a good bat.

Is Reyes the worst player (position player) in baseball to rate using OPS+? I don't know if he is the worst, but one of the worst. Just about everything not included in OPS+, Reyes is very good at. Defense, base running (and not just on steals, didn't one of those base running metrics rank him near the top?), he is even durable now after the hamstring problems of 04. He has missed 12 games in the last 3 years total, and some of those were after the Mets clinched in 06. He missed 1 game in 05, and 2 last year.

Maybe OPS+ does a worse job on a Molina brother or something, but I think Reyes is near the top.

Not only all this, which I agree with completely, but the trend, especially in 2007 is for his OPS to become more heavily weighted toward OBP. If that represents a legitimate change in approach and improvement, OPS+ underrates Reyes a little just based on his hitting. Even over his entire career, counting the seasons where he was poor at getting on base, Reyes is slightly under league average in OBP (.331 against .338) and SLG (.426 against .430); he's pretty balanced as a hitter, and if you think Reyes' true ability more resembles 2005-present than his career numbers, OPS+ does ever worse for him than it does for the other player mentioned in the article, Jimmy Rollins. Especially in 2007, where Rollins was significantly below-average in OBP and well above average in SLG.

Is Reyes the worst player (position player) in baseball to rate using OPS+?

Not just Reyes, but Rollins too. The obvious thing that OPS+ misses is that he plays every day. OPS+ is a great stat to judge future performance, but for actual performance it's absurd to only use a rate stat. One of the most valuable things about Rollins is that he leads off for 162 games and plays one of the two most crucial defensive position on the diamond for almost every inning of the season.

Rollins played 1441 1/3 innings last year out of a possible 1458! That's just insanely valuable for a player of his offensive ability, especially when the backup who logged the other 17 innings was Abe Nunez.

This, incidentally, speaks to one of the inadequacies of using VORP to judge the MVP. The Phils didn't have a replacement level SS offensively or defensively...they had Abe Nunez. And the fact that hypothetical replacement SS abound in VORP does not mean they were coming to Philly. If Rollins had missed time or sat out a few days, it was Nunez, a below replacement level player who would be coming in.

Edit for clarity.

Agree on that, but Rollins, while a good base runner, isn't as good a base runner as Reyes, and probably the same can be said defensively as well. Rollins also probably has more value tied up in his slugging than OBP, at least compared to Reyes, so he doesn't get as hurt there.

But yeah, OPS+ doesn't do a great job telling the story of Rollins either, but I think it does a better job on him than Reyes.

Not say say either one is better, just that I think OPS+ underrates Reyes more than Rollins.

You guys are overlooking the more important question: who IS the most overrated player in the NL?

My gut reaction would be one of Colorado's hitters, like Holliday or Atkins, since most people have gone back to not caring about park factors. Either that, or a SD pitcher.
   18. cardsfanboy Posted: April 05, 2008 at 02:07 PM (#2731741)
my gut would be someone like Pedroia(not necessarily unproven), someone on a major news market team that is young and unproven. I imagine the most overrated player will play for the Red Sox, Yakees, Dodgers, Diamondbacks,
   19. JJ1986 Posted: April 05, 2008 at 02:16 PM (#2731748)
Francoeur has gotten into conversations as one of the better right fielders in the league despite the fact that his numbers aren't very good. I'd probably pick him. Either that or someone defense challenged like Carlos Lee.

I'd probably go with Carlos Lee. If his defense is as bad as the metrics say, he's barely above average, if at all, but he's considered a star, and paid like a superstar.

Given that Jimmy Rollins was in no way the best player in the NL last year but he won the MVP he must be pretty high on the "overrated" list. Juan Pierre must also be up there considering a lot of people seem to think he has the bat to play in left(!). Ken Griffey. Brandon Phillips.

My baserunning metrics have him as roughly +5 runs as a baserunner last season, which is very good - he's had batter seasons, though. I'd say him (and Rollins) are two of the best baserunners in MLB right now.
   24. Sparkles Peterson Posted: April 05, 2008 at 05:46 PM (#2732047)
Okay, OPS+ sucks for this. Look at better metrics then.

Jimmy Rollins was a two-time All Star before he stopped basically sucking, and won an MVP when he should have probably been third on his team.

Two years ago, Reyes would have been his main competition for most overrated player in the league. I'd still say he's in the discussion, as people talk about him as the most valuable young player in the league or the one guy you'd want to build a team around and his performance simply doesn't warrant that.

"Given that Jimmy Rollins was in no way the best player in the NL last year but he won the MVP he must be pretty high on the "overrated" list."

I'm not sure why you would say this. It was very close between Wright, Pujols, Rollins and Holliday for who deserved the award, IMO. As such, it's hard to say that Rollins is pretty high on the overrated list simply because he edged out others who were at most only a small amount better than he was. Here are the top scores in WARP3 from 2007:

David Wright 13.1
Albert Pujols 12.8
Jimmy Rollins 11.7
Matt Holliday 11.5
Chase Utley 10.8
Jake Peavy 10.3
Miguel Cabrera 9.9
Hanley Ramirez 9.8
Carlos Beltran 9.8
Brandon Webb 9.0
Brad Penny 8.8
Adrian Gonzalez 8.5

Were there any other advanced metrics besides WARP that showed Rollins being anywere near that close to the top, though? I haven't seen any. I have something of a difficult time taking seriously a stat that says Adrian Gonzalez was the 9th-best position player in the league (and ahead of Chipper Jones).

Wrong. Utley had a great season, but he missed 30 games. That's a huge chunk of the season. Rollins played in every single game. I don't know who else you think was more valuable to the Phillies in 2007. I'd like to see your evidence for this third phantom phenom.
   28. cardsfanboy Posted: April 05, 2008 at 06:00 PM (#2732078)
remember some people are rating only on ops+ so Howard with his atrocious defense is the third. You know the guy that won the previous MVP underservedly so.

"Were there any other advanced metrics besides WARP that showed Rollins being anywere near that close to the top, though?"

Most metrics I've seen would have made Wright the MVP. However, my point is that it was close in most of them, and even if Rollins was not the most deserving, the difference between him and the best player in the NL was not huge in 2007.

Contrast that to 2006 in the American League, when Justin Morneau was undeservedly (according to WARP3) given the MVP. He truly was not his team's MVP:

Derek Jeter 12.2
Grady Sizemore 11.0
Carlos Guillen 10.4

Johan Santana 11.1
Joe Mauer 10.2
Justin Morneau 8.9

James's Handbook has Reyes +70 bases and Rollins +61, far and away the best in baseball. Why not just add baserunning bases to OPS? This is not a rhetorical question. Really, is there a statistical reason not to do this?
   32. salfino Posted: April 05, 2008 at 06:23 PM (#2732118)

The average NL 1B had about a 117 OPS+. And, yes, he played good defense, but Gonzalez was only 7th among NL first basemen in VORP.

By add baserunning bases to OPS, do you mean add them to OBP, SLG or both? The thing about OPS is that you're adding two fractions with different denominators - one is divided by at-bats, the other by plate appearances. So you're further complicating things if you just add baserunning bases - and first you have to figure out what kind of bases they are.

[Also, base running bases don't have the added benefit of advancing the runners ahead of them; if I hit a single or a double, I move up any runners on base ahead of me. If I take an extra base on the basepaths, that doesn't move anyone up. So you have to weight them differently.]

Really the best thing to do is convert everything to runs and go from there, because everything in baseball is related to run scoring. OPS is a shortcut anyway; once you're making OPS more complex, you're better off starting from scratch with something like linear weights.

But you've moved yourself up, which should count for something. Add the 71 bases Reyes took to his OPS (which side it goes to doesn't matter to me) and you get .879, which seems to me, eyeballing it, a better approximation of Reyes's 2007 offensive value.

The plodders like Burrell get 16 bases taken away (for example).
   36. Colin Wyers Posted: April 05, 2008 at 09:07 PM (#2732234)
I would say that you're probably overrating the value of baserunning that way. Now, I don't have access to James's baserunning stats, so I can't test this idea directly.

But here's how I do it. According to Baseball Reference, Jose Reyes was worth 2.7 Batting Runs, so right around a league average hitter. Then I take a look at his runs above/below average in baserunning, which works out to 4.45. (I parse my own baserunning stats from Retrosheet event files - it's something of a work in progress.) So, 7.15 runs for Reyes. (If that figure sounds a little low for Reyes, it probably is a bit - he was better in 2006 and 2005 by my metrics.)

Burrell, on the other hand, was worth 24.3 runs hitting, and -4 runs on the bases, for 20.3 runs overall.

You can then go ahead and factor in defense and a positional adjustment on top of that. I'm pretty sure that once you factor in defense and position, Reyes is the more valuable player.

I find it pretty shocking that Reyes' baserunning in 2007 was only worth around 4.5 runs.

This site has .44 runs for a caught stealing and .19 for a SB in the 2007 NL. If I plug in the numbers for Reyes:

78*.19 - 21*.44 = 14.82 - 9.24 = 5.58.

That's 5.58 runs if Reyes is merely neutral as on the basepaths outside of stolen base attempts, which I also doubt.

Those are "generic" weights. The Run Expectancy values I use take into account the number of outs in the inning and which base a runner is stealing, which could be skewing the numbers against Reyes. Like I said - he did better in 2006 and 2005, and so I would expect those numbers to improve again in 2008.

I didn't realize you were calculating on a play-by-play basis; that sounds like an awful lot of work.

Do you account for non-SB running value, like going 1st to 3rd or scoring more frequently than average from 2B?
   41. Colin Wyers Posted: April 05, 2008 at 10:43 PM (#2732280)
It's certainly not a SMALL amount of work, but the computer handles a lot of it.

I look at advance rates on singles, doubles, ground ball outs, fly ball outs, and other events. (Stolen bases are "lumped in" with advancing on wild pitches/passed balls and other such oddities; that might not be entirely correct but it's what I came up with.) The general spread in talent appears to be ten runs above/below average. Reyes at 4.5 runs is good, and 2007 was a down year for him.
   42. CrosbyBird Posted: April 05, 2008 at 11:01 PM (#2732286)
Reyes at 4.5 runs is good, and 2007 was a down year for him.

Out of curiosity, what does 8.5-9 runs of hitting difference look like? It seems to me like there's a world of difference between Jose Reyes and Pat Burrell on the bases, but for that to amount to less than a single win's worth of difference over a full season is hard for me to wrap my brain around.
   43. Colin Wyers Posted: April 05, 2008 at 11:18 PM (#2732291)
The other issue here is opportunities; in 2007 I have 434 baserunning opportunites for Reyes, as opposed to 111 for Burrell. Reyes had quite a few more PAs than Burrell, and he leveraged himself into a lot more baserunning events than Burrell did. If you made Burrell run the bases as much as Reyes did, then the distance between them becomes a lot more drastic.
   44. CrosbyBird Posted: April 05, 2008 at 11:25 PM (#2732295)

I never realized the opportunity difference was so dramatic. Doesn't that skew the average high, though, if the better runners get more opportunities than the worse ones? It seems like we'd get a sense of what the average opportunity looked like, but not so much what the average runner looks like, no?

Well, that was certainly uncalled for. In any event, the replacement level used in WARP is widely considered to be unrealistically low, resulting in it significantly overrating players with a ton of PAs like Rollins and Gonzalez. (It doesn't actually have Gonzalez ahead of Jones last year, though--Chipper had a WARP3 of 10.8, so it looks like Rich just missed him on his list.)
