If Super Bowl 50 is really Peyton Manning's last professional game, he's going to leave behind a game that has been irreversibly changed by his career. That's not a commentary on his legacy in terms of his statistics or success, although those are wildly valuable. And it's not a talking point about the actual physical style with which he played quarterback, although Peyton can count Russell Wilson, Andrew Luck and Marcus Mariota among the future NFL quarterbacks who attended the Manning Passing Academy. And it's not even about Manning's ubiquitous presence as a pitchman, how he somehow transitioned to becoming the Dad Joke Michael Jordan.
