dlunc Halladay and Lee are 2 aces on one team. Of course Halladay is maybe best in baseball. Hamels is doing great right now but history tells us that he isn't as good as he is doing. Oswalt is past his prime.
Comparing the 2 staffs, i would take halladay and lee from philly, but then beechy and hudson from braves. Beechy has dominating stuff. He is a man. The real difference is the bullpen. Braves have the bullpen that every team wants. I think the Braves are better pitching staff from top to bottom and it shows in the stats. BUT you do have to factor in that we play half the games at turner field. But it is hot and humid there every night so how much of a pitchers field is it really? The dimensions are not as crazy as some are like San Diego.
I think Hamels will fall a little in 2nd half, Oswalt will stay at upper 3 ERA. Oswalt is not an ace anymore. It's not comparable to Smoltz, Glavine, Maddox who were in the same team throughout their prime.
