The only reason I think he has a chance is that slowly the overall fanbase is beginning to recognize that spygate was overblown. The further we get from that dreadful day in September, the more people will realize that stealing signals is not cheating or even proscribed by the NFL. With the dawning of that realization there will come a reciprocal appreciation that the penalty was too heavy (although no-one will support restitution as 2 1st round picks would only make the Pats even better).
BB has had to overcome the opprobium of some of his peers, the public censure/disowning of his actions by his boss, the calumny of the mediots and the hatred of the uninformed football fans. He has used the ultimate insult to fire up one of the most effective and efficient teams ever.
I realize that some will never vote for him, but casting an eye around the rest of the league, none have come close to what BB has achieved this year. Its only a question of how long it takes for the unjust reputation to fade. I also think that the extremists (Easterbroken-record etc.) painting the Pats as the evil dark force actually help highlight the ludicrous complaints of the mediots, and that helps the objective and rational football fan see things more fairly.
