Mayfield seems like he's had an inconsistent career. Maybe half of it is his own fault, but it's hard for me to tell. He started good in Cleveland, was on fire when Greggg was head coach, then poor with Kitchens, then great in 2020, then injured but without anyone at the time seeming to realize just how much. Cleveland was stupid to ditch him for Watson, but he looked so bad in Carolina that Darnold at his lowest point was still competing for starts. Then he looked good as a backup on a team that should have been good enough for the playoffs but got derailed by injuries, and went to Tampa because they didn't really have anyone else to replace Brady.
All in all, I'd grade Mayfield as a "pretty okay" QB with flashes of "really good" now and then. But he got drafted as a 1st overall, and it's been a long time since he scared me like a 1st overall should. I think he's got a less flashy Kirk career arc. Doubted, discarded, earns his respect, but will never carry a team the last few steps into a Super Bowl.
