There might not be guarantees, but there are characteristics that a head coach must possess. I think that's true with the head of any organization. Guys like Reid, Parcells, Vermeil and Shula win year after year, team after team, owner after owner. Romeo sucks everywhere. McDaniels is looking like a good coordinator, bad coach. Ain't nobody here knows much about his head coaching ability and the fact that BB had success with a new job is irrelevant. Jim Plunkett won a Super Bowl at 36 after a terrible career. That's not the norm and not a justification for going after old terrible quarterbacks. Nagy might be really great. I just am not sold yet that he'd be my first choice.
