"What Gailey does instead is to change the formation and personnel, but running the same core concepts from each, to give you fifteen different looks of what is, at its most basic function, the same play. For further reading, I suggest you take a look at BuffaloRumblings."

"Gailey's offense is complex only in the sense that it uses a variety of different personnel groupings, formations and motions to execute the same play calls."
Gailey's offense was also often compared to the Pats' offense in that it ran a lot of stacked sets of WRs and rub routes. His offense was better, in some ways, though. His running and screen game was unmatched. Nothing could stop his offense if he had a Ryan Fitzpatrick that could throw past 15 yards. I always believed that's why we had so much trouble scoring points after the first half of the season- Fitz's arm was dead. I don't think it had much to do with the offense being "figured out."
