It's hard to dislike that team, good job overall man. My only two suggestions is try to deal for some more SB to replace Joe Crede, if you can get a good price, and find a better closer than Brian Fuentes, who can hurt you at Coors Park.
Otherwise, I don't see any severely big holes. I think you should be more or less good to go.
