Well, for starters, we have what we have heard about his time in Carolina. But we also have early indications here, including players who have commented on the more disciplined approach and the "earning the right to win" philosophy. He is also putting a greater emphasis on leadership within the team.
To me, his style was very evident in the draft - not just in the picks and maneuvers, but also in the way the Bills communicated before and during the weekend.
