I think he is mad because the Sox wanted to move him to make room for ARod (and honestly ARod plus Ordonez would have been a massive upgrade to the team). He needs to get over himself.
As for the Cubs, they have Clement, Sosa, Walker, and others in the last year of their deals, plus I believe Prior can go to arbitration this off season. Unless Nomar has a huge second half, I would wager he will not get a $60M offer from the Cubs.
Oh, I enjoyed watching the Yanks pull a panic deal and dump Contreras for a guy who will not be as good a pitcher as him by the end of this season.
