SP's are better. I would dump the two headed fourth starter for a single guy. If Radke, Garcia, Webb, Weaver or Maddux are still there, they would work. I have seen them all do well in the half dozen 2006 leagues I've been in. All they have to do is go .500 and they did all right.
RP's-Donnelly not reallt good enough. He gets rocked by RH hitters, which is what you don't want. Correira(?), who I think you had at one point, is better on your team than Calero. What good is a RH specialist when almost all your pitchers are RH? The answer is not much. You need a halfway decent R(2) to add depth and Correira helps you out there.
IF-Your IF is great offensively and defensively. Should help out your pitchers quite a bit. Pods is OK in LF. I don't understand the CF situation. I wouldn't keep Kotsay just because of Damon's "D", if that is what you are doing. I would go with your Lofton DH platoon before keeping Kotsay just for the "D". You see fewer LH pitchers in Fenway, and he doesn't hit RH all that well.
