Votto +2, Rolen +3.5, Bruce +2, Phillips +1, Hernandez +2, Cueto +1.5, Wood +2, Leake +1 That's 15 "wins" worth of WAR improvement from 2009 to 2010 from 8 players. Obviously some players (Dickerson, Harang) contributed less this year than last so that eats into the gains a little bit. The other big factor at play here, LUCK, isn't quite so easy to quantify unfortunately.
