Until the exact reason for his drop in performance/measurables, I don't see how the Sox could do more than 1 year at a discount. If Rodon wants the Sox to roll the dice without solving the mystery, he has to compromise, a lot. Personally, I'm moving on from damaged goods, and looking to fill a rotation spot with something more dependable. A bad plan is to reserve a rotaion spot for a question mark if you have other options.
