Jake Peavy to the White Sox?

This is the FIRST time I have written about the Chicago White Sox. All of the buzz this morning has been about the Sox trading for San Diego Padres P Jake Peavy. Peavy is owed $60M through 2013. The deal is basically done, Peavy just has to OK the trade (he has a full no trade clause). The Sox would send pitchers Clayton Richard and Aaron Poreda to the Padres, they are the two top pitching prospects in the Sox's system. I would think they would have to include a few more prospects. My question is: Why are the Sox doing this? The Sox have pitching, despite how bad Gavin Floyd, Jose Contreras, and Bartlolo Colon have been. The Sox are also an aging offense, who look like they only have a few good seasons left in them. This move would not make the Sox a World Series contender, let alone a playoff team. They still can not hit (sounds familiar see Cubs).

In the end, I do not expect this deal to get done. Here are my reasons:
1) Peavy wants to pitch in the NL, he enjoys hitting, and facing weaker line-ups.
2) The Sox would have to give up more, like SS Prospect Gordon Beckham.
3) The Padres should be suspicious of Sox GM Ken Williams, who has a history of fleecing other teams for good players. Examples: the Carlos Quentin trade with the Diamondbacks and the John Danks trade with the Rangers, just to name two.

Furthermore, if this deal were to be completed, it would not be the end of the world. The Sox are not going to be a realistic contender over the next few years anyways. I would rather see Peavy go to the Sox than the Brewers (the team other than the Cubs, he said he would waive his no trade clause for). In the end, I still hope Peavy comes to Chicago as a Cub. I just do not think we have the prospects to get the deal done, I would be willing to part with Jeff Samardzija and Jake Fox, but not 3B Josh Vitters, who is the heir apparent to Aramis Ramirez and supposedly the guy the Padres really want from the Cubs farm system.
