Ben isn't stepping into the throws because, without a run game you aren't going to get 3 or 3.5 seconds in the pocket. Do you think Ben just stopped being Ben and decided to try 2 and 3 yard passes? No, of course not, but he knows his O-line isn't holding up under any type of pressure from the defense so he he's resorted to the short throws and an occasional deep ball. Since there's no running game, there is absolutely no impact of a play-action pass (of which the Steelers are last in the league in running) so Ben sits in the gun and tries to win games. He can probably beat the Bengals with Burrows out but the Colts and Browns probably win those games.

Did Snell get hurt? He was doing pretty good, the O moved the ball, I think they scored on that drive and then...pfft he was gone..
