I thing the obvious solution is to start Sams next game and see what happens. If he can chew up more yardage and convert more third downs with his speed, despite our shitty line play, then he's the answer. My preference (and i think Snyders) was to use him as a red zone QB, but if we don't have a running game with Hubert and Waters, were going to have to sacrifice some passing ability for more mobility.
Again though, the whole premise of this thread is that QB play is about 10 on the list of things that lost this game. Our defense rough ridin' sucks. Period. Sams might provide marginally more offense, but our crap D is going to make it very hard to win 6 games this year.
