Debated with my father-in-law about this last night. Forget even calling him the GOAT (though, I think so). Peyton, IMO, is one of, if not the most single impactful player to ever play the game. Take Peyton out of the game, and the team (Colts or Broncos) went from contender to bottom of the pile. However, I will concede, Denver's D was key to winning against the Panthers. Imagine Peyton with a good all-around team for his entire career.
