(CBS Sports) The Kansas City Chiefs came up short versus Tom Brady and the Tampa Bay Buccaneers in Super Bowl LV, losing 31-9. With his 7th Super Bowl ring, Brady has now won more championships than any other player in the National Football League, putting an end to any of the “greatest of all-time” debates. The loss comes as a shock to the Chiefs and their fans. Their almighty offense was absolutely nowhere to be seen, as Patrick Mahomes and the offense failed to score a single touchdown the entire game.
