I am going to get called a Bill homer for this but I have to get it out there, you just can’t make this question into an either or situation there are WAY too many variables. Both Bill and Tom are called the GOAT, and for good reason, what they accomplished together is so mind boogling better then any one else in NFL history it defies reality. They have been to more Super Bowls then any other FRANCHISE. Take that in for a second. We have a player and a coach that when working together in 20 years is better then what any other team has done in 100.
My issue with the people saying it’s all Brady, look at Bill‘s sub .500 record without Brady is the lack of context. Great coaching does not necessarily translate to wins, especially if you have two years of needing to clear cap space in there Which both 2000, and 2020 were. What you have to look at for coaching is are they disciplined? Every week this year the commentary points out they are the lowest penalized team in the league. Are they playing hard, focused, and in every game even when out talented? 2000 they lost 11 games but how many of those were less then a score? This year has been a mixed bag as I give them a pass for the Denver and 49ers games, while the recent Ram game was a fiasco. Then you have giving the Seahawks and Chiefs all they could handle and beating the Ravens.
Do your players buy in and do what they are coached to do? How many people do you need to hear say the attention to detail in New England is unparalleled, the playbook is calculus compared to pre algebra elsewhere, or that Bill called exactly what would happen a week before the game? It’s not one or two examples either if you read the books that are out or listen to former players it comes up again and again that Belichick has an uncanny ability to predict what other teams will do. Players have a feeling of confidence that if they execute the game plan they will win.
Game time decision making is also a major plus, I mean yeah he is human and you can point out the mistakes he has made but I would bet a lot of money he is +80% right which in a game of inches is all you can ask. How often have you seen BB coached teams sprint to the line, or make an adjustment to a crazy formation, or just know the rule book better then the other team? Honestly its more shocking to see it when it doesn’t happen. Bill gets more out of the margins then any one else alive and gives 53 players more, and better, chances to make a play. That’s all coaching can do, after that it’s up to the players to execute which brings me to Tom Brady.
There is no doubt Brady is a HUGE reason the pats have 6 rings. I think BB with an average QB has 2, just from having a good team get lucky having all of the breaks fall the right way. He sets up enough teams with good position year after year that it’s a dice roll that falls the right way. Brady is the amplifier that gets in those make or break situations and +80% of the time does just enough to get a W. What makes Brady so good? It’s not his stats he has only lead the league in any particular stat a couple of times in his 20 year career. There have been plenty of games where he has thrown back breaking ints or fumbled away a W, or won a game 13-3. How many games have they won rushing for 200 yards or the defense being otherworldly? It’s easy to say TB12 is the GOAT and hides everything bad but the truth is for 95% of most games he is just good, sometimes even very good but not elite wins every game by himself. Then you get into the 4th or that situation where you need a kill shot.
I seriously question if Tom has split personality disorder cuz normal Tom is a quiet mild mannered dork that says all the right things and never does anything wrong. Then psycho Tom comes out to play and that man is a ruthless stone cold killer nobody wants to Fu#$ with. He isn’t out very often but that 5% of the time when the chips are down and you gotta have it....Man nobody in the history of football does it better. I think without Bill, Brady wins 2 SB just thru sheer “I am the baddest MF to ever walk the earth” but doesn’t have the teams around him to get 9 shots at the prize. It’s only together thru BB’s building of solid fundamentally sound teams giving Brady so many chances that Psycho Tom was able to capatilize on that got 6 rings.
So who is more important? I would say it’s about 55% Bill as he affects 53 players, including Brady, about 40% Brady as i doubt anyone else could be as consistently clutch, and about 5% Kraft for the world class facilities and staying the fu#$ out of the way. Point is I am grateful for 20 years of dominance the NFL will never see again and appreciate the hell out of every patriot that made it possible. I wish Brady well any time he isn’t playing the Pats cuz he deserves it and I am not sad it didn’t work out until the end of his career here. Keeping it together for 20 years was impressive enough and I have memories for a life time due to BOTH men.
He must be" improving" because the last time I remember looking at that stat when some in the media were touting that Rodger would end up as the GOAT, that 4th quarter figure was in the SINGLE digits.
