Peyton Manning is one of the most likable athletes in professional sports so it is easy to overlook how insanely competitive he is both on and off the field.
It's that competitiveness that led to him being named Sports Illustrated's"Sportsman of the Year" despite being 37 years old.
The intense anecdotes include cursing out opposing coaches, his sneaky first quarterbacks meeting in college, and picking the brain of his biggest rival.
Even when he gets a day off from practice to rest his ankle he still wears a helmet to listen to play calls and watches game film in the ice tub.
He once showed up to the Colts practice facility at 4:00 am after a night game because he wanted to get work in before an 8:30 am charity engagement.
Outside of missing the 2011 season, Manning never misses a game.
