I think Dabol makes way more sense than Frazier, I doubt Frazier is hired and only receives interviews so teams can compete requirement by NFL. You either want a offensive coordinator coming from a pass happy offensive team that puts up huge points or a team who gets after the QB and leading the league in pressures & sacks. This a pass happy league and no one cares about bend but don't break defences
Frazier will get plenty of interviews for NFL requirement only, I would love to see it happen because I believe the Bills would receive a 3rd round compensatory pick
