Seriously? Carroll has taken his team to the playoffs 3 years out of the 7 he has coached in the NFL and won 2 playoff games. Sounds pretty good to me compared to what Miami has done the past decade. And it isn't like Carroll has had superstar players to work with, yet.
Carroll hasn't had a winning season in the NFL since 1998. He has coached 6 years and have had a winning season twice. Not saying Carroll is a bad coach, but he isn't one of the NFL's top head coaches.
