To a point, I agree with you.
I live in Boston and can tell you the organization did not fail Mac Jones. Mac Jones failed Mac Jones by thinking he was greater than the team. His persona on and off the field is what made him lose favoritism.
Trey Lance looks like he was a glorified combine stud. Couldn't beat out Jimmy G and Mr. Irrelevant Brock Purdy. Lance was a guy that was supposed to change the game.
Zach Wilson looks to be a spoiled rich kid that didn't get his way. His family is more highly touted than him at this point should speak volumes. If he is going to turn it around, Payton is the only person who could do it.
Jared Goff is one that comes to mind; garbage with the Rams and has recreated himself in Detroit.
