‘In year one under Daboll, the Bills leaned heavily on the one back, one tight end formation (3 wide or 11 personnel) as it was their most popular personnel grouping. A good portion of the league uses that formation more than any other in their offensive play calling as well. The issue for Daboll was that he couldn’t play off of that personnel package with other groupings with great effectiveness due to the limitations of some of the players he had at his disposal.’
