Peavy to White Sox? or would he prefer playing for the NL ?

The trade is approved by San Diego, but does Peavy want to play for the American League? Last time we checked, he's said he'd rather play in the NL.

And if Peavy passes on the White Sox.... could the Cubs make him an offer he can't refuse?

We Cub fans are used to hoping for unlikely scenarios.
Come on, Peavy! Give us a hint of your intentions (to join the Cubs) in your inevitable interview. Maybe just a brief nod to the North Siders; a "Holy Cow, this was a tough decision, but...".

Go Cubs.
