It is OK. Vlad, Chavez, Furcal, and Berkman (when healthy) are your big guns on offense.
I am not happy with the rest of the bats, however. Mauer looks to be injury prone and unproven. Hafner was solid last year, but only has one good year under his belt. Iguchi is unproven in the majors. Lane is having a good spring, but he is a risk. Rowand and Ford are good players, but I think they really only have one good year under their belts as well. Giambi could bounce back, Reed could be bad or good, and Burke is up in the air. Overall, it doesn't excite me.
Sheets is a solid #1 starter, but I hate that he plays in MIL and won't get a lot of wins. Mussina will get a lot of wins, but his ERA was terrible last year. Bonderman could break out, but he plays for the Tigers, which hurts. I like Buehrle as your #4 starter. And Penny could be huge if healthy. Nathan and Aquino are decent as a closer combo.
Overall, I say middle of the road, with Vlad/Chavez/Berkman/Sheets as your main keepers. I say get a better closer over Aquino. And, maybe a better 1B in case if Hafner falters. If Hafner, Rowand, and Ford do better this year, it could put you towards the top of the standings.
Curious... when did you draft Berkman?
