You could pair Belichick with four or five other contemporary QBs, and the results would've been similar (maybe six, maybe less, maybe more).
You couldn't name a single other contemporary coach to pair with Brady that would've produced six championships.
Add to that: Belichick isn't just the coach, he runs the whole show.
The truth of this debate? Football is a sport for blue collar people, and blue collar people will always favor the guys actually playing, the guys doing something on the field, versus the coaches and executives who are all just BS artists by comparison.
Nobody on this thread would pretend to be a better QB than Brady, but apparently a whole slew of you know how to build and coach a team better than Belichick. Just laughable.
