The flaw on that is there's no Brady without BB. No way to exclude.BB's influence.
Would Brady have beaten the Rams without BB's D? I think not, but that's just opinion.
Nonetheless, back to topic. There is a 'way.' I don't want Flores to copy it page for page, but I do like many concepts
I thing there are a few flaws with your flaw :)
First, I was dealing with facts and one of the flaws with the flaw is that Brady couldn't be Brady somewhere else is pure speculation. If the Steelers drafted him the 7th, with the quality of that organization, we might be talking about Brady's 10 Super Bowl wins right now. Imagine playing with WRs like Ward, Wallace, Holmes, Brown, Smith-Schuster a consistently good running game and great defense. We saw what he did with Moss 2007. Or Brady goes to the Ravens, Giants, 49ers etc...we may still be talking about 6 Super Bowl wins. Pure speculation on my part, it's easy to do. The truth is nobody knows for sure. I fall on the side that someone as great as Brady is would have found a way to excel regardless of which team he started with, barring injuries of course.
Second flaw is see with the flaw is Belichick is "NO QB whisperer" and does not have a history of maximizing a QB's talent. In fact, almost all QBs coached by BB have had more success under different coaches.
Bernie Kosar (record as starter)
30-17 under Schottenheimer (1985-88)...Kosar 22-25 years old during those years
12-16-1 under Carson and Schofner (1989-90)...Kosar 26-27 years old
11-18 under Belichick (1991-93)...Kosar 28-30 years old
Mike Tomczak
21-10 under Ditka (1985-90)...Tomczak 23-28 years old
15-12 under Cowher (1993-96)...Tomczak 31-37 years old (included a 10-5 season in only season as starter)
4-4 under Belichick (1992)...Tomczak 30 years old
Vinny Testaverde
12-2 under Parcells (1998-99)...Testaverde 35-36 years old
16-15 under Belichick (1993-95) Testeverde 30-32 year old
Drew Bledsoe
32-27 under Parcells as Pats coach (1993-96)...Bledsoe 21-24 years old
12-10 under Parcells as Cowboys coach (2005-06)...Bledsoe 33-34 years old
26-20 under Pete Carroll (1997-99)...Bledsoe 25-27 years old
14-18 under Gregg Williams (2002-03)...Bledsoe 30-31 years old
9-7 under Mike Mularkey (2004)...Bledsoe 32 year old
5-13 under Belichick (2000-01)...Bledsoe 28-29 years old
* Parcells was 56-39 (.589) and 3-3 (.500) in playoffs with Testaverde and Bledsoe; whereas BB was 21-28 (.429) and 0-0 in playoffs.
Matt Cassel
10-5 under Todd Haley (2010)...Cassel 28 years old
stats: 262-450, 3116 yards, 27 TD, 7 int, 93 QB rating, 26 sacks
*10-5 under Belichick (2008)...Cassel 26 years old
stats: 327-516, 3693, 21 TD, 11 int, 89.4 QB rating, 47 sacks
* What's important to note with going 10-5 under BB in 2008 had mostly to do with schedule. AFC East played the NFC West and AFC West as two divisions matched up against in which the Pats went 7-1 against, swept the Jets and split with the Bills and Dolphins. Only one team out of the 8 in the NFC and AFC West had a winning record which was the Cardinals who went 9-7. The reason the Cardinals went 9-7 is because they went 6-0 in their own division, 3-7 outside of their division. The two teams the Pats played against in the AFC based on how they fared the year before (Colts and Steelers) they lost to. The Pats still were 5 wins less than the year before, of course 16-0 is tough to duplicate regardless of circumstances. However, the ease of schedule is how the Patriots could go 11-5 without Brady just like it allowed Miami to go from 1-15 to 11-5 that year.
Jimmy Garoppolo
6-2 under Kyle Shanahan (2017-2018)...Garoppolo 26-27 years old (included going 5-0 after being traded to a 1-10 team in 2017)
2-0 under Belichick (2016)...Garappolo 25 years old
To claim that without BB there is no Brady, to me, embodies that notion that BB made Brady into a player he couldn't have been under a different coach. Factually, Belichick doesn't have a history of doing that. In fact, just the opposite when compared to some of the really good coaches in the league. And who in their right mind would think that Cassel and Garoppolo learned more from Belichick on how to play QB than from watching, being around and being in meetings with Brady?
Third flaw in the flaw is the assumption that without BB there is no Brady. It is far more likely without Brady there is no BB (as we think of BB) and Brady would still have managed to become an elite QB like Johnny Unitas or Drew Brees. When Brady played his first game in 2001 Belichick's record up to that point:
Cleveland (1991-95)...6-10, 7-9, 7-9, 11-5, 5-11 and Fired!
New England (2000-01)...5-11, 0-2 (Bledsoe gets injured), Brady leads the Pats to 14-3, including the playoffs and Super Bowl win.
If Brady wasn't already, well Brady (as seen above BB is not a great QB coach), and Belichick has to rely on a lesser QB if Bill Belichick's name was brought up most fans would think, "Who?" or at best he is a great DC, but lousy HC. The Pats only carried Bledsoe and Brady on their roster in 2001. They carried John Friez (13-25 as a career starter) and Michael Bishop (9 total passes in NFL career) in 2000.
So if the Pats don't have Brady and finish the way they were headed with Bledsoe in 2001, another 5 or so wins, would Belchick have been fired again at the end of the season? Would Belichick have ever been offered another HC job? Belichick had a 41-57 win/loss record and losing record in 6 of 7 seasons at that point when Brady started first game.
The last flaw of the flaw I see is there is a tendency to deny the impact some QBs have on other players as a coach themselves even though they aren't referred to as a coach. There is no doubt the best assistant coach Belichick ever had wears a #12 jersey and also plays QB on Sundays. All the reports, interviews, etc...I've read/seen about Brady in practice is he is a perfectionist and the most competitive person his teammates have seen. Similar to what was said about Michael Jordan. He demands perfection from himself and others. When a receiver doesn't run a route precisely, Brady will get on them or encourage better than any coach can do and have a greater impact than if it were coming from a coach. Peyton Manning was similar in that way. Do it right in practice and it will carry over to the game.
I would argue Brady has had more of an impact on Belichick being regarded as a great coach than Belichick has had on Brady being a great QB, by far. The win/losses support that.
Belichick as HC:
261-123 = Record overall
31-11 = Playoffs; 9 Super Bowl appearances; 6 Super Bowl titles
Belichick as HC without Brady starting QB:
54-63 (.462) = Overall record as HC without Brady
41-57 (.418) = Overall record as HC before Brady makes 1st start
36-44 (.450) = Record as Browns HC
18-19 (.486) = Record as Pats HC without Brady
1-1 (.500) = Playoffs (wildcard game win with Cleveland)
Belichick as HC with Brady starting QB:
207-60 (.775) = Record with Tom Brady
30-10 (.750) = Playoffs; 9 Super Bowl appearances; 6 Super Bowl titles
Coach Flores can do everything the "Patriot or Belichick way" but his success will in large part depend on whether Flores gets a QB that more resembles Tannehill or more resembles Brady. The former will result in a coaching change in a couple of years; the latter may result in a Super Bowl title or multiple. Of course, the Brady's don't come along often so we may get a QB somewhere in-between so I'm hoping Flores is just a better coach than BB.
