24. Ron Rivera, Carolina Panthers
The Panthers showed flashes last season, and seemed to have nowhere to go but up. Late game failures and miscues were the tell tale signs of a young football team, not necessarily a coach in over his head. That said, Rivera still has much to prove.
The rest of the rankings
Rivera made a handful of questionable rookie coaching decisions but he also fell victim, in these rankings at least, to a defense unable to close out games. If he can turn it around this year and get to the playoffs I'd imagine he'll be closer to top ten this time next season. (John Fox, by the way, is ranked number eight for his adaptability. )
