The Sox would lose all the rest of their remaining fans if they traded Colon off now. Everyone would scream white flag, and that we were quitting while still in the race. Being 5 games out of a team that is way overachieving, and that people are just waiting to see when they fall apart, they would be crucified in the national media as well.
I think it would depend who the trade yields. If we got someone who could step into the rotation right now and contribute, I don't think it would be that bad. After all, Colon hasn't exactly set the world on fire this season...
IF we got 3 of the pitchers that we have talked about I would be in favor of the deal, BUT, it would be a PR nightmare if it happened.
