This. What happened with Mac - some on the player himself, some on the "coaching" he received, some on the lack of weapons - certainly didn't help BB's cause. But there's plenty of dumb shit that led to his demise in N.E. The Patricia fiasco. Terrible, big-footing draft decisions like N'Keal, Strange, Tyquan, JoeJuan. Assuming - separate from Mac - that installing Matty P at OC was a good idea, and wanting to run that back despite the catastrophe. The lack of motivation for developing/acquiring elite weapons during the valuable rookie QB window, the lack of foresight in terms of how long Brady could play at a high level, the apparently pervasive notion in the building that all you really need is an average QB to compete for a championship. I mean, it's a lot of stuff.
Also a lot - the amazing, unprecedented and genius-level work BB brought to game planning and culture and, for awhile, roster construction. Given the sustained success over 20 years, I'll take the good, the bad and the Harry all day long.
