Aaron Rodgers isn't the most outspoken quarterback in the NFL, but he might just be the most competitive.

The reigning MVP and four-time Pro Bowler has called himself "obsessively competitive," claims to remember every interception he's ever thrown, will sometimes go days without talking to his teammates because of locker-room card-game disputes, and last year dropped an f-bomb on "Celebrity Jeopardy!" after missing a question. (He went on to win, of course.)

This sort of competitiveness is what helped an undersized high schooler with no Division 1 scholarship offers go from playing junior-college football to winning two regular season MVPs and a Super Bowl MVP. It's what makes the Packers a Super Bowl contender year in and year out, and what makes Rodgers arguably the best quarterback on the planet.
