I agree it would be a "dick" move and would hurt their credibility. But I can't blame them if they do decide to move them. Because in the end let's face it, their assest's. And the team should use them as such.
First of all it's Buchholz.
Don't let his spot in the rotation fool you. Buchholz on most other teams is no lower the a #3. The fact he is in the #5 spot is a testemet to how good the Sox potential starting rotation is. And there is a reason his stock is probably higher then it's ever been. And it's not because he isn't good.
Did anyone else bang their head on the screen while reading this last sentence? I had to go back twice to make sure I didn't miss a sentence.
But no I doubt they have "given" up on him after one bad year. He had a setback this year, and it happens. Wasn't the first it happened too, and won't be the last. This season will be important though. If he doesn't rebound this year, then there might be a cause for concern IMO.
