I'd go for Haren and I'm a guy that's been okay with sticking with what they have. Back issues are tricky, but he still made 30 starts and was better down the stretch (3-3, 3.31 ERA in Sept). If fully healthy, this is a top of the rotation starter, and even if it flares up some, he's likely to be solid mid rotation guy. I've always liked Haren. Put another way, I'd rather have Haren (assuming the return isn't all that much) on one year at an inflated amount, than give a 30 something guy like Dempster an inflated 3 year deal.
