There's a big question of how often Fick is going to play, considering how heavy the Braves are in the OF - he's probably your weakest link. Other than that, the team looks pretty good, although having a SS at util is rarely wise. You could probably pick an OF off waivers who'd hit better than Cabrera. Or, of course, you can play Josh Phelps, who could easily hit 30HR's this year. He seems to be going in the last few rounds of most 12-team drafts, which is a steal for that kind of production. Imagine how useful he'd be if he qualified for a position!
Your rotation looks decent too, although it drops off sharply after Shilling and Millwood and Guardado. You're gonna have to keep your eye on the waiver wire early in the year, and don't be afraid to pick up any young pitcher that has a hot start.
