Eventually, you've got to be accountable for losing 5 out of 6. He didn't lose all 5 to Belichick. He blew it. It's time for a fresh start.
Eventually we have to remember that only 1 of the 12 teams that enters the playoffs gets to leave them happy, and six AFC championship appearances is an achievement of significant proportions. And getting this far with a rookie QB is pretty impressive too. We're supposed to fire the guy for being only the second coach in NFL history to win a playoff game with a rookie, but not being the first to win 2?! Doesn't make sense. He did great for 17 games this year and lost to the best coach in the league, this would be the stupidest of all possible times for a "fresh start", consistency on the sidelines builds success.
Fans in sports are way too eager to fire coaches, who that's available would do better? What coach out there could have beaten Belichick with a rookie QB at all (which Cowher did) much less in the AFC championship game? Give me names.
