That's 6 trips to the AFC champ game, that's a lot of success. Belichick outcoaches everybody, if we fired everybody that got out coached by the best in the game there'd be 31 job openings.
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.
