I would let Josh sit another week fully healed to play the Fins. One more game won't matter. Jags are more than likely gonna get smoked by Pittsburgh who is playing very well right now. They'll be out of the hunt and angry by the time they get to Buffalo and take it out on our rookie QB. Josh will be anxious and try to do too much, especially against Ramsey who said some pretty foul things about him and hasn't really backed up anything.
Then again, if your franchise QB can't handle adversity is he really the answer? Iron sharpens iron, right? Personally I'd sit him one more game.
