Aside from Mahomes and Rodgers? There are a few that are borderline but probably wouldn’t make it.
Matt Stafford comes to mind for his impressive stats and his Super Bowl ring. Kirk Cousins has revitalized his career In Minnesota. Lamar Jackson is the only one not named “Patrick Mahomes” or “Aaron Rodgers” who has an MVP. That’s the best I can come up with.
How about CMC? Give it to an RB for a change. He’s having a hell of a year, leading the league in rushing yards and total TDs, and he’s certainly the most valuable player on one of the best teams in the league. I think most people were counting him out after his injury history in Carolina, but he’s persevered and managed to be a real threat.
