It's not like we have a young backup QB we need to take a look at.
Ben is cleared to play and the last thing we need is to bench him after he blew 2 consecutive games with horrible interceptions. Do we really want him going into the offseason stewing on that? It could eat away at him all offseason and shake his confidence knowing that he helped cost us a playoff spot.
I'd much rather give him the ball again and give him a chance to redeem himself in the last game of the season against a division rival. Give him a chance to go out on a high note and get his confidence back.
