It's hard to really figure out what was the real Scott Rolen last year. Apparently he felt good early in the year when he couldn't catch up to anyone's fastball. However late in the year he was far from an offensive liability. I think he can still hit if his shoulder allows him, so I'm good with him coming back if he says he's good. If it's in a bench/spot start role you'd be getting a proven player and you wouldn't have to worry about him wearing down.
