I have soured on Bill since Butler and I don't hide it but nobody is disputing Bill is an all time great coach. As of now he is the greatest IMO but Reid may come for the crown. At least of all the coaches I have seen since I have been watching football (20 years).
While I was never a massive fan of Bill purely because of his personality, I liked him as much as I liked any coach of my fav teams and I used to always believe in one thing above all and that was Bill always did what he thought was best for the team. I may not have always agreed with his decisions (OMG the horrible DB round 2 reaches) but I never questioned that and therefore always supported him.
That all changed with Butler for me because nobody will ever convince me that benching Butler was best for the team. What came out of the Dynasty just enforced that since he was not even accountable enough to his players or owner to explain to them the reason.
His greatness, which is fully deserved, (to me anyway) is very much separate from the undisputable fact that he made 3 massive blunders in the last few years: 1) Benching Butler, 2) Getting rid of Brady without a plan which resulted in 3) Replacing him with Cam/Stidham/Mac.
To me that is unequivocally due to hubris. You can even see it in his older videos (2000s) vs later on. He went from a somewhat reserved guy but also respectful and engaged with people (press conferences, interviews) to someone who barely said anything and every interaction of him was unprofessional at best to just downright rude. That is clearly someone who thought he was not accountable to anyone and could do whatever he wanted.
Vrabel once said that in the early years players used to push back on stuff they disagreed with him on. Can you imagine him allowing that in the later years?
