Zero personnel issues with the defense. It's all in the scheme. Too few defenders in the box all game long to expect to consistently stop the run. B1G play could be ugly if Bo doesn't adjust.
Charles Jackson + Jonathan Rose MUST be in the game. That is personnel issues. Our best open fielder tackler isn't in (when one of our biggest weaknesses is open field tackling).
Still way to much trouble covering a running back out of the backfield. They look around and wonder who was supposed to cover the guy. One of three things. Players aren't buying in and are playing for themselves. The scheme is to difficult or they aren't very bright.
