Hard to argue against Brady being the GOAT and I doubt anyone wins that many SB in that amount of time.
Belichick would need to win a SB without Brady to be considered the best coach in history.
Not that hard to argue.
3 SB wins under spygate. Pats fans have deluded themselves thinking it was no big deal, however, it's on par, if not worse, than the 2017 Houston Astros cheating scandal.
I mean, read this:

The league office lifer, then 49 years old, had been commissioner just 18 months, promoted, in part, because of Kraft's support. His audience wanted to know why he had managed his first crisis in a manner at once hasty and strangely secretive. Goodell had imposed a $500,000 fine on Belichick, a $250,000 fine on the team and the loss of a first-round draft pick just four days after league security officials had caught the Patriots and before he'd even sent a team of investigators to Foxborough, Massachusetts. Those investigators hadn't come up empty: Inside a room accessible only to Belichick and a few others, they found a library of scouting material containing videotapes of opponents' signals, with detailed notes matching signals to plays for many teams going back seven seasons. Among them were handwritten diagrams of the defensive signals of the Pittsburgh Steelers, including the notes used in the January 2002 AFC Championship Game won by the Patriots 24-17. Yet almost as quickly as the tapes and notes were found, they were destroyed, on Goodell's orders: League executives stomped the tapes into pieces and shredded the papers inside a Gillette Stadium conference room.
That's massive. Read about Ernie Adams in the article, an employee hired solely dedicated to cheating. It was SO bad, the league itself tried to cover it up. It's why they were so harsh on deflategate - owners were furious that the Pats got away with it.
Then, take two SB gifts - one from Seattle, one from Atlanta. Both were losses that were gifted wins because of sheer coaching stupidity. The games were locked up, and the coaches gave it back.
Tuck rule, hand in the neutral zone, etc, so many calls. In addition, played in the worst division in the NFL for 15 years, and had the rules were actually changed to benefit Brady from gettting hit.
So, yes, you can make the counter. I'm not sure that he's not the best, but spygate and all the above context needs to be part of the discussion, but they are always ignored.
