I'm getting tired of arguing this but you can't just keep making stuff up.
He had a 3.48 ERA last year. The stress fracture sucked, but it's not like he didn't show us anything. And in his last 12 starts before hitting the DL he had a 2.97 ERA and was 6-1.
If you want to argue that he's not able to stay healthy, fine. But to say he doesn't perform when he does pitch is simply not true.
