Mullen altered his play calling. His offense was still pretty limited without a running QB threat unless he had just top notch talent. He made it work mostly at Florida with a pure passer (Leak I think? or Leake?), but even then he relied a lot on Tebow coming in for short yardage and goal line packages. But definitely, he at least could make it work with Russell against lesser talent.
I don't understand what Barbay has done in one off season to confuse our offensive line so much. Certainly they had their issues last year, particularly against talented pass rushers, but they usually looked like they were on the same page.
