He was DFA'd because he is horrible not because he was a bad teammate. It's not like he was sent down to work on things but rather they simply didn't want him on the team anymore.
All I'm saying is its a rumor I've heard around here, and I'm inclined to believe it. As I've said, his defensive ineffectiveness probably had a lot to do with it too. But if he was being a problem in the clubhouse, I could see that being the straw that broke the camel's back.
