I think they blew it with Epenesa and Basham, trying to help Frazier scheme, when there were offensive players available to impact the team. McDermott/Frazier overruled Daboll on draft day
How about building an offense suited for Buffalo weather? If not, forget about home field advantage in playoffs. The aerial attack is good from Sept-Nov, but in January you need to be able to grind out yardage.
