Now, let’s be clear: achieving one feat that evaded Tom Brady’s teams does not pass the goat-horned crown from Number 12 to Number 15. Patrick Mahomes will still have his work cut out for him to be justifiably called the greatest quarterback of all time.

Before Tom Brady was anointed the "G.O.A.T.," San Francisco 49ers quarterback Joe Montana was considered the best signal-caller ever by many. Over time, with his consistent Super Bowl appearances and wins, Brady eventually overtook "Joe Cool" as the game's all-time best.
