I really don't think they're going to get a team to take AJ off their hands and pay a chunk of the contract, but who knows.
As for the rotation, I'm right there with you. I never would have thought, going into the season, that Garcia, Colon, and Nova would be this effective for such an extended period of time. I'm also pretty shocked that this team has a legitimate chance at winning 100 games. I really thought this year was going to be similar to 2008 ... and I'm obviously thrilled to be totally wrong.
The one place I disagree is that I'd be quicker to resign Garcia than Colon. I think Garcia's success has a better chance to translate into next year.
