I would say he's a good buy low candidate RIGHT NOW. I would do it before tomorrow's game. Tomorrow his value could balloon with a solid effort.
I'm a JJ owner who will be sitting him tomorrow ( I also picked up MBarber recently), so you can take it with a chunk of salt.
No pain no gain. I'd take the chance on it, his value is about as low as it'll get barring a re-aggravation of injury.
I hate LJ Smith!
