Whatever back issues (spasms) he has are not something that have had too much of a negative impact on him considering that coming back from the DL he only pitched under 6 IP one time in 10 starts and that was 5.2 IP. Small sample size no doubt, but his history of back issues aren't something that have hampered him all that much looking at his career. In his previous nine years as a full time starter he averaged 208 IP/year and only had under 210 IP three times (127 -03, 208.2 - 08, 181.1 - 09). His DL stint and his increasing age are certainly matters of concern, but he's been remarkably durable throughout his career. I think he'd be a valuable 3rd or 4th pitcher for the right price. Anything over 2 years I'd shy away from though. And what does him being small have to do with anything? That's the same dumb reason that Mississippi State and Ole Miss passed on him and he ended up playing at a lame JUCO down the road.
