No, and no. His problem was throwing across his body, which put too much torque on his shoulder. Obviously, with the way he dramatically falls off the mound after every pitch, he hasn't changed anything. IIRC, he actually verbally refused to change his mechanics the offseason before his last long stint on the DL (2005?). I really don't see him getting another shot at it for that reason. I say leave him where the mechanics are really not an issue.
