Things like (and I'm paraphrasing): 'Jimmy G cost his hardworking teammates a trip to the Super Bowl', 'The 49ers can't win with Garoppolo', that kind of thing.
What stood out to me (as it did last year after LV) was how reluctant people (fans, media, and ex-players) are to criticize Mahomes. The only person that I have heard do it is Warren Moon.
