Since you have Arod, I'm assuming you got a top 3 pick.
How did you get Peavey, Oswalt, Howard, and Peralta, and Zambrano? Those guys are all at the very LEAST 4th rounders.
I would pull the trigger on that deal in an instant. Oswalt is good, but Zambrano lost 15 lbs this season in an effort to win the Cy Young this year. He is a solid number 2. I'm not 100% sold on Lackey, but he should be a solid #3.
Pierre is gonna be huge this year. Lidge I always think is overrated, but he is a top 5 closer at the very least.
