Nobody said it isn't the most important position, just fans place too much credit/blame on QB performance because it is easy.
What are you even trying to say? That Kirk Cousins isn't Aaron Rodgers or Peyton Manning? Outliers much?
Yeah true, never thought of that before. That is definitely true.
And Rodgers/Manning aren't "good QB's" they're generational talents that are all-time greats.
I don't think any other player in the NFL should win an MVP other than the QB. There's no position on the field that comes close to being as important to the team.
