First, BB doesn't walk on water. But he is one of the best NFL coaches ever. Bitch about his missed picks all you want, but no one other than Ozzie Newsome picked as good. Polian was good as well and he also pcked late every year. Where BB excelled is teaching and developing players, especially UDFA, unheralded FAs, and later round draft picks. After 20 years of picking in the 28-32 range, he build some tremendous teams and dominating defenses.
Second, I've been to Patsfans and still go there occasionally, and I call bullshit on the place being full of anti-BB posters. Just as you confuse disapproval with hate, you apparently don't kow the difference between being angry at something and giving up on someone. For diehard Pats fans like me, the team is almost like an extended family, not quite but almost. You don't like everything everyone does and when one family member doesn't do what you think they should you can get REALLY angry, but they are still family.
Look at it this way, if your kids did something you strongly disapprove of, do you hate them? Do you disown them or just complain for a while but realize they are basically
good kids at heart?
It still boils down to Pats fans appreciate what Brady did and believe that he and Brady performed magic together. You have to diss BB in order to make Brady look like it was all him, all by himself, and he did it in spite of BB.
The question is, why do you need to do this?
