His final season here, Bill Belichick was like the guy who wanted to break up with his girlfriend (in this analogy, the Patriots are the girlfriend, not Bunny) but he was too chickenshit to do it himself so he completely checked out mentally, acted like a total jerk, and then let the Patriots do what any self respecting organization would do and drop his sorry ass.
His problem is once he got on the open market, he was nowhere near the catch he thought he was. He got on his hands and knees to beg the Jets for a job but they told him to go screw. Atlanta allegedly came close, but now they definitely feel like they dodged a bullet.
