The Phillies have a great staff, but Cliff Lee is overhyped right now because of last year's postseason. He is generally always pretty mortal for stretches every year, including last year after he was traded to Texas. Oswalt can be pretty hittable at times, too (Halladay hasn't been hittable since he was in grade school, though). The Braves' rotation is pretty solid. A lot of people are expecting Hanson to have a huge year. Hudson was a Cy Young contender last year. Beachy just had arguably the best spring training of any pitcher in baseball. Sure, he's not going to keep that up in the regular season, but he looks great as a #5 starter. The Braves' bullpen is a lot better than the Phillies with Lidge out.
With Utley out, Atlanta has a much better starting 8. If Utley doesn't get healthy, they'll be depending on Howard to carry the offense. Werth is gone and Rollins has been declining for 3 years. I would love to have Victorino, but he's not capable of carrying an offense. The Braves, on the other hand, have Chipper (who hit .380 this spring), McCann, Uggla, and Heyward all capable of carrying an offense, and they have the ROTY favorite batting 8th.
