With Sunday's high-profile matchup between the future Hall of Famers Tom Brady and Peyton Manning on tap, the 37-year-old New England Patriots quarterback acknowledged Monday that as he has aged, he's allowed himself to reflect on the rivalry with his 38-year-old Denver Broncos counterpart.

"But as you mature a little bit and realize this could always be the last one, then you do. It's pretty special. "[Manning has] been one of the greatest players to ever play.
