You can't cut Carr next year, so who can fix him?

Nope. Gruden was 3-2 in 2021, before they S-canned him for being a parochial d-bag. Their scoring offense was nothing great that year, before or after he was fired. And then he looked like hot garbage the next year playing for McDaniels.
Sorry get your story right. JG did not get S canned he resigned. Yes he was 3-2 at the time and then they went on to finish 10-7. they more than likely would have done better if he had not resigned probably matching that 12-4-5 record they had in 16
