So, listening to a number of local (if not always reputable) sources, here is what has been "reported" about Kazmir:
He went on the DL with a quad strain, but in reality it's a mental stint on the DL. Word is Kazmir's elbow hurt him for most of last year, and he re-configured his motion to compensate for this. Well, fast forward to this year, and the elbow no longer hurts, so the change worked - except as a result of his change to his delivery he is mechanical, not fluid, and he is constantly fighting himself, throwing across his body, aiming the ball, etc.
Word is Kazmir has not seen eye to eye with pitching coach Jim Hickey from the time Hickey arrived, and it started when Hickey moved Kazmir from one side of the rubber to the other. It seems like Kazmir has been in a constant struggle to let loose ever since Hickey has become the pitching coach, and the D Rays brass may be contemplating letting Kaz go on a rehad assignment in Montgomery or Durham to try and "re-find himself".
Bottom line - he makes $10 million per year, he has a slight frame, and there is a fear he's damaged, so he has zero trade value right now. The Rays are going to have to go to work on his head, and hope he can go back to the Kazmir that just let's it fly.
