A big problem is people look at the result and not the reason and just want quick fixes that don't exist. Jimmy can't win Super Bowls when his team is one of the most talented teams in the league, he's also one of the more injury prone QB's in the league. When the team sucked and Brady did bad, people said get rid of him. He went somewhere with talent and won a ring and had two MVP caliber years which proved wrong the idea that he was the issue. We have since not had a QB who was even at his 2019 level. We blamed Cam in 2020, when Stidham and Hoyer went in they were worse. Now we are having similar issues and Mac is the guy and it's supposed to be his fault.
When something is going on for 4 seasons (2019, 2020, 2021, and now 2022) and people leave and look better elsewhere, the problem is more than one guy being an issue.
