I would not be surprised to see the Red Sox trade Daniel Bard at this point. Sure, he fell apart as a starter, but there is definitely some team out there who is willing to buy him on the merits of his career. I think that there are going to be many teams who are willing to give up a good deal for a cost controlled guy with a 100 mph fastball, who could potentially be a franchise closer.
If the Red Sox think there is something seriously wrong with him mechanically, they could probably net enough value for a #2 starter for him-- even after such a terrible season.
