You must have missed the whole Cooper Rush having 5 starts in '22 because Dak was hurt. How come McCarthy gets a pass this year but Moore doesn't in '22? He was McCarthy's scapegoat and everyone knows it. The irony is his name has been floated to replace McCarthy in Dallas.
You're discounting Payton's history, he coordinated the Giants 15th ranked offense led by Kerry Collins to the Super Bowl in 2000. He also turned around Dallas' 2nd worst passing offense and made it into a middle of the pack passing offense with a whole bunch of nothing at QB. He was a up and coming offensive mind, not just that he had a strong drive and could motivate players.
No one is comparing Allen to Glenn as people. Yes they are complete opposite. Glenn won't be the abysmal failure that Allen was but he runs a very similar scheme to Allen but with less success. lol. Plus there's the whole offensive coordinator carousel dilemma that even Payton Manning sees as a big problem for young QB's,
