The thing with Clement is this.. Last year he was forced into the ace role in the rotation because of injuries to Schill and Wells. I'd still like to see what happens if he pitches in the #3 slot that he was supposed to be pitching in. Remember, he was the DLowe replacement and shouldn't have been lined up against #1 and #2 starters for the entire year. I think it just wore him out - and that shot to the head didn't help any (he noticably changed his landing spot in starts afterwards and was flinching a lot).
Now, that said, he is the odd man out if we need to trade a starter for a centerfielder. I think he could be the ace on a lesser staff in any other division and I think it would be a good pickup for one of those teams.
