The real question is how much damage do those two pitchers are they going to do to our final win total. Bill James projected Dice-K at 173.0 IP with a 3.85 ERA added. Lackey is 227.0 IP with a 3.89 ERA added. I think the two are obviously going to pitch better, but how much better are they? Dice-K has induced four swing and misses this year, and is getting absolutely torched by lefties. Lackey is going to be the Red Sox's AJ Burnett. He looks old, his stuff has declined, and now he can't throw strikes. Bill James has these two for a projected WAR of 6.5. I don't see league average pitchers in these two, they are probably good bets to finish with 5+ ERA's.
With the rest of the team performing at his projected standards, they are picked to finish with 95 wins. Where are they going to make up those up? This team will finish south of 90 wins.
