Good question, I'll bite:
Ryans is new, brings great energy, kind of unproven but looks promising
Stefanski has quietly settled the Browns down. We Bills fans B word about McD & injuries, would the Bills have won 11 games with 4 different QBs and 3rd string OTs?
LaFleur did well without Rodgers, when nobody thought he would
Campbell has certainly turned the Lions around
I'm not sure if those 4 coaches are better than McD, but they're worthy of praise.
