Bellicheck is completely overrated as a coach. He was 36-44 with one playoff appearance in 5 years at the reigns in Cleveland. His first season in New England he was 5-11, and the team was 1-3 (if I remember correctly) when Mo Lewis changed the course of NFL history.
Without that hit, Brady never sees the field for possibly years, if ever, as a Patriot.
When Brady goes, so will Belly....he is smart enough to know when the gravy train ends.
