With a win this weekend over the Baltimore Ravens at Gillette Stadium, Brady will earn the right to play in a fifth Super Bowl, a total matched in NFL history by only one other quarterback: John Elway. No one ever has played in six. No one has won more than four. If Brady can close his career the way he has closed so many games during his illustrious 12 seasons, he could earn his place as the single greatest quarterback ever to play the game.
