Replace Cam with even say, Dalton what would our record be?
Point being, Cam and the offense has been so bad, that despite that, Bill is going to lead this team to likely 7-9. Even with an average QB like Dalton, we would likely be in the playoffs.
It means that Bill can lead a team to the playoffs with an average QB and who knows, even further and doesn’t need a HOF caliber QB to win.
Okay? So?
Many coaches have succeeded with average QBs. How would going 7-9 this season with Cam be an accomplishment?
Matt Nagy took Mitch Trubisky to the playoffs with a 12-4 record in 2018 without that great of a roster.
Sean McDermott took Tyrod Taylor to the playoffs without a great roster
Bill Cowher took
Neil O'Donnell to the Super Bowl in 1995
Lovie Smith took
Rex Grossman to 13-3 and to the Super Bowl
Not to mention, Belichick has a large sample size of coaching seasons with average/slightly above average QBs, and it kind of points to him
not being the coach that can win/make the playoffs with anybody. He's had Vinny Testeverde (Pro-Bowler), Drew Bledsoe (who made a Super Bowl and was an All-Pro), Matt Cassel (who made a Pro Bowl), and Cam Newton (who made a Super Bowl and was a former MVP) - who have all made the playoffs without Belichick - and across those 8 seasons, he had 2 winning seasons, 1 playoff appearance. Different teams, many years, to account for personnel/roster.
I am not saying Bill Belichick isn't a great coach, but this argument/head canon that "Belichick can win with any average QB" does not hold up to scrutiny AT ALL.
It's still a players league, and having a great QB is HUGE. If Rex Ryan had Tom Brady in 2009 and 2010, Jets win at least 1 Super Bowl with those teams.
