This thread prompted me to compile an adjusted set of Support Neutral Lineup-Adjusted Value above Replacement totals for the last three years. I added two important custom adjustments to produce what I'll call SNEVAR (E for Everything): one for defense, using the numbers for true defensive value (park adjusted-UZR) I just calculated in that other thread, and one for competitive imbalance, using my adjusted standings for each year.
The first thing that's obvious is that when you are talking about pitching
talent, you should be looking at two seasons and no more. Of the dozen most valuable pitchers over the last two years (weighted 4-5
a la Marcel), no less than five did very little in 2007 (Greinke, Lee, Jurrjens, Danks, Lester) and a sixth was middling (Lincecum). Of the 30 most valuable pitchers from 2007-8, you had Webb, Hudson, Matsuzaka, Sheets, Young and Marcum providing almost nothing this year and Peavey, Lowe, Shields, Kazmir, Hamels, Harang, and Meche all dropping way down in value.
You can see this yourself at FanGraphs or BP; just check out the leaderboards year after year and look at the volatility . Being excellent for one year may be a fluke; two shows real talent; three or more and you are adding other (highly valuable) attributes into the mix.
Some comments on four pitchers:
Cliff Lee. He's quite clearly, right now, one of the four or five best pitchers in baseball in terms of results (a further analysis to factor out
luck is for another day). Halladay and Sabathia are the only guys that rank ahead of him in both of the last two seasons. Greinke's two year total beats him, and then it's either him or Lincecum. Some "joke," eh, boss?
John Lester. He's been only a borderline ace each of the last two seasons, not approaching the super-elite just mentioned (a group you would round out with Felix Hernandez and, if healthy, Johan Santana). And that's because he really rather sucked for his first six starts in 2008 and his first
ten starts this year. Yes, there's a pretty good argument that he didn't become this stud until start #7 of 2008, and that the bad start to this season was the result of his big workload increase the previous one. And yes, if you toss those 16 starts out, he probably does rank with the aforementioned. But how many other guys could you make a similar argument for? Until he actually has the ace season, he's just an ace-in-waiting.
Josh Beckett. He has not ranked higher than
24th in SNEVAR in the last three seasons. He has been reasonably consistent, though, and over the last three seasons he ranks 17th weighted 3-4-5, 20th weighted 1-2-3. In my book that makes him a very good #2, with the stuff to pitch like a true ace for stretches of decent length, but too much inconsistency to establish himself as such.
Clay Buchholz. He was 40th in SNEVAR/GS last year (minimum 15 starts), which means he's already a #2 starter on a bad team or a #3 on a good one. So the view on him is correct. If he merely sustains that until he's a FA, you would trade him for:
3 years of Roy Halladay or Zach Greinke
4 years of Sabathia, Lincecum, King Felix, or Lee.
Which means that Greinke and Lincecum are the only star pitchers you would trade him for (since they are 3 and 4 years from FA respectively). Now, if the consensus was that #2 / #3 was his upside and that he's already reached it, you could absolutely justify making a trade where you would lose on total VORP or SNEVAR or PSWTSA* because you had acquired the guy you needed to start and win Games 1 and 5 of a playoff series. But I think we all agree that Clay has that upside, too. So if you trade his 25 SNEVAR for Roy Halladay's 9 or King Felix's 13 or 14 and Clay is a true ace for just 2 of his 5 remaining seasons, you are just unspeakably hosed. You probably lose if he has just one ace season. Personally, I don't want to gamble that Clay Buchholz is never going to advance from #2 / #3 to ace (a world of difference between that and gambling that some minor leaguer will never be an ace.)
