It's the same problem we had with Eric Martin. Martin could slice through most OTs and get into the backfield on most every play, but that's not what he was allowed to do. He had to create the containment pocket with the rest of the line most of the time, and that simply doesn't play to his strength.
I want you to go watch Eric Martin specifically in the play that Dennard Robinson got hurt.
I want you to go read the quote you responded to, specifically the part I highlighted in bold, underlined, italics, red, and made bigger so it's more difficulter to miss.
One play does not disprove a trend. It is Bo's defense, and it has been since at least the VA Tech game in Blacksburg.
After you've gotten what I'm on about there, go watch Michigan's game against Western Michigan. Three down linemen against a five-man front and two seconds after the snap, the Chippewa QB has pressure in his face. Why? Because Hoke's scheme allows his D Linemen to put pressure on the QB. Bo's doesn't, lately against even immobile QBs.
