Loved seeing the 4th down stop again. On second look, Smith had that bootleg snuffed out, should Wiscy have gone that route. I think it had been said earlier that the bootleg was open, but I think that play was well designed and a good call.
From watching the video a couple more times, it looked to me like Whaley shot through the gap and had the play stuffed no matter which way it went. I think if O'Brien would have kept the ball on the naked bootleg, Whaley would have drug him down right away also. If he didn't get him, I think Smith would have.
