If Jay has really limited mobility and can't make all the really important throws, sit him. Not a defense you get healthy against. McCown can at least keep you in the game. If this was last year, I'd say play Jay. But what if Jay reinjures himself by trying to play through this? Or tweaks his groin and he isn't close to full strength as a result for the remainder of the season. Will make it hard to properly evaluate Jay and I don't think Emery has his mind made up. Really affects the draft and what you do with Jay, Peanut, and Peppers. Or maybe Jay is out and this is a continuation of Trestman trying to fool the Lions into preparing for Cutler.
