For those of you that are interested, David over at Fangraphs has updated his site and he now has WPA data all the way back to 2002. That includes daily game graphs and season totals, and should have soon fully integrated game logs for each player, plus much more.

Here are a few snippets for each year:

2002 (rotation +853.7, bullpen +811.1, batting -64.8 / +351.6 not counting pitchers)
-    Pujols (341.3), MattyMo (280.2), & Izzy (299.4) led the team; Rolen posted a 134.7 in 55 games; Simontacchi (189.8) & Andy Benes (175.0) surprisingly effective
-    Matheny (-129.2) & Robinson (-128 in <200 PA's) were the team anchors on offense; the three rookies, Pearce & the two Smiths, combined for -168.8 in 23 starts; no real ciphers in the bullpen
-    NL MVP: Bonds (983.1), Walker (610.9), Vlad (557.4); NL Cy Young: Gagne (683.9), Randy (661.2), Smoltz (581.5); AL MVP: Thome (604.3), Giambi (557.3), Bernie (498.0); AL Cy Young: Koch (496.5), JC Romero (458.0), Percival (452.8) [top starter: Pedro (431.7)]

2003 (rotation +201.1, bullpen -109.9, batting +308.8 / +605.8 not counting pitchers)
-    Pujols (571.9), Woody (211.1), & Izzy (187.7) topped each group; JD (293.3 in 100 games) & Jimmy (280.7) excelled as well; Hitchcock & DeJean combined for +137.5 in 56 innings [too little, too late]
-    Matheny (-266.6), Simontacchi (-153.1), & Fassero (-136.1, bullpen only) earned Waste of Flesh honors; Borbon Jr. (-47.3, 4 IP) & Wilson Delgado (-102.9, 77 AB) exhibited excellent suckitude-per-game-played ratios [Note: Fassero was actually break even as a starter.]
-    NL MVP: Bonds (750.6), Pujols, Helton (539.6); NL Cy Young: Gagne (731.4), Schmidt (553.2), Prior (510.1); AL MVP: Delgado (658.4), A-Rod (493.5), Giambi (442.9); AL Cy Young: Loaiza (539.6), Pedro (518.2), Foulke (473.4)

2004 (rotation +838.9, bullpen +938.3, batting +622.8 / +1041.2 not counting pitchers)
-    MV3: Pujols (575.6), Edmonds (521.4), Rolen (376.5); Carpenter (278.7) & Izzy (374.2) paced the pitching staff - every starter had a positive WPA & all of the front six in the pen were +50 or better
-    Matheny (-171.0) & Edgar (-164.8) were the worst hitters; erm, ah, um ... pitchers stink at batting? (What did you expect? We won 105 games.)
-    NL MVP: Bonds (1267.8), Berkman (576.9), Pujols (575.6) [note: Drew (487.5, 7th)]; NL Cy Young: Lidge (616.6), Gagne (607.6), Smoltz (551.7) [top starter: Schmidt (477.6)]; AL MVP: Sheffield (495.7), Mora (458.2), Manny (451.6); AL Cy Young: Nathan (569.6), Santana (553.0), Rivera (504.5)

2005 (rotation +1166.1, bullpen +650.6, batting +83.3 / +500.8 not counting pitchers)
-    Pujols (358.6) not nearly as dominating as I thought he was; Edmonds (269.9) & Walker/Sanders (700 PA's = +369.5) still solid; Carpenter (547.7) & Mulder (339.7) set the example in the rotation; Izzy (252.9) & Al Reyes (248.4) spearheaded a bullpen that had its top 6 at +50 or better
-    Diaz (-145.2), f'in Cedeno (-101.4) [I don't think his name can be said any other way], & Mahoney (-89.5) provided plenty of suck-for-the-buck; no real complaints among the starters => Morris' -43.9 is still respectable; Burger King (-162.9) made sure his save chances were flame-broiled
-    NL MVP: Chipper (521.4, 109 games), Delgado (486.2), D. Lee (437.9) [Andruw (306.2)]; NL Cy Young: Clemens (680.6), Willis (638.6), Pettitte (587.4), Carpenter [Note: Houston's Big 3, Roger / Andy / Roy (506.8), all topped +500]; AL MVP: Ortiz (847.6), A-Rod (572.9), Hafner (474.8); AL Cy Young: Halladay (487.3, 19 starts), Santana (485.6), Street (410.2)

I'm sure I can keep myself busy there for a few months at least. (I have a simple job with a lot of free time for web browsing.) If you're interested in a different take on what Valuable means, take a look.
