If he commits multiple penalties today, then he should be benched for the rest of the season.
Give Sweeney a chance. Smith can be the motivational locker room guy on the sidelines.
Also, I know that Senorise Perry & Patrick DiMarco are Special Teams aces, but can we please give T.J. Yeldon more playing time. I know that he's just an average running back, but he's a damn good receiver. Remember our lone touchdown against the Patriots* this season? He had two big catches on that drive. Let's give our offense all the weapons it has.
