As much as it pains me to say it, Bellicheck likely deserves the official award this year. What he did with all of the key missing pieces to end up where the Patriots are vying for a spot in the title match-up is pretty damn spectacular.
If the AFC had not been so awful this year I would agree with you. But how many great-to-elite teams were in the AFC? Broncos/Pats/.....maybe Bengals. Not exactly murderers row.
