I think this is the most probable outcome. Is he a franchise QB.......no. Can he function effectively in a system where the D only gives up 15+ points/game......yes. What you saw on Sunday is what will happen more often than not if he is asked to win a ball game from behind. But boy is that defense really good.
...........and please don't bring up the "Minnesota Miracle". Great play but lots of parts went into that for that outcome to occur.
