I had the same thought as the guy above: BA is your one big weakness, to the point where you'll probably lose it just about every week. That said, I think the offense is solid aside from that and the pitching staff, across the board, is great.
Are you punting the holds cat? I don't see a middle reliever in there. So if I were you, I might shop one of your mid-level SP--Shields or Lee maybe--for a top-tier middle reliever. And see if you can move one of your real bad BA guys like Dunn for a well-rounded type like Dye, Ad. Gonzalez, etc. Good luck!
