I’m not sure Bill is undisputed GOAT coach right now.Unless BB turns it around, he will not pass Shula and Landry for most wins, he will not have proven that he can win without Brady, and lastly will be viewed as only one of the greatest coach ever instead of undisputed GOAT.
Meanwhile, Brady's comparative greatness has surpassed BB. He has proven he can win outside the Patriot Way. He has obtained most of the major records for his position. He is largely considered the undisputed GOAT by a country mile.
Two years ago, we didn't know who was greater. Now we know.
Maybe he is if you look at rings only. Other than that what exactly makes Bill greater than say Vince Lombardi? I don’t know. Lombardi is an icon in not just football but all of sports and even has the freaking trophy named after him. Is Bill greater than Shula? Shula has more wins right now and his coaching tree is way more successful. It’s debatable how well Bill has done developing coaching talent. I guess we’ll see what happens to Josh this year. Gibbs? Gibbs won with 3 different QBs and none are in Brady’s league. Reid took two completely different QBs and systems to Super Bowls. Walsh and Landry were pioneers of the sport. John Madden has the highest winning percentage of all time and BB is not that close to that mark. Unfortunately Bill also has Spygate in his story.
Where Belichick does shine more than others is his ability (with a few exceptions coughnkealharrycough) to make lousy players decent and decent players good. That’s why he can find gold in the UDFA swamp more often than others.
But yeah it’s very much disputable who is GOAT coach. Bill and every other top coach is great at some things and inferior to their peers at others.
That’s why I put Bill on the very top level of coaches with a few other historical great coaches for now. Rebuild this team to a contender with Mac Jones and not Brady and he starts to separate himself from the pack. Imo.
