It did. And now that his booty partner (Tom Brady) is gone, he's being exposed for what he really is. And here's to hoping he decides to hang it up or croaks before he surpasses Don Shula's all time wins record.
If Wikipedia is right, Belichick has 300 wins and the record is 328 by Shula. Bill is 71 years old and has his rings. To break the record, he realistically has to coach 3 more years at the minimum. The way his team is playing, I don't think there is any reason to believe they will win 10 games next season or even sniff the playoffs in the AFC East.
Good chance he retires after this season if the Pats finish with 5 wins and have no franchise QB.
