I dont think its the biggest factor in seeing what type of year Dontrelle will have, but it is one indictation. My point is, good luck improving your ERA switching from NL to AL.
Also, I think you underestimate the Central. Yes, the Indians are an offensive powerhouse, but the Twins, White Sox and Royals have already showed they are going to be active this offseason. Ths Sox got O Cab and Quentien. Not huge additions but offensive contributors. And dont be suprised to see the Twins add more onto Delmon in what they get from Johan. And the Royals, though they still arent an offensive juggernaut by any means, are trying to make some cheap udgrades.
Plus, I think they White Sox will still have a pretty decent offense. I dont think it will work, but Kenny Williams is still trying to win now. I also think(much like 2005), 2007 was a freak year.(though they had very opposite results) I think the Sox still have a good offense, just had an awful year.
Is pushing for President Obama to pass a law requiring all citizens to be Chicago White Sox fans and make October 1st "White Sox Day" where we all dress as our favorite player. It maybe socialist, but I don't care.
