From NBC SportsWorld: Two years ago, Peyton Manning had the greatest statistical season of his numerically dazzling career. You remember — he was 37 years old and two years removed from a horrible neck injury. People went into the season more worried more about his safety than his passing numbers. He threw for an NFL record 5,477 yards, threw an NFL-record 55 touchdown passes and was named The Associated Press Most Valuable Player for the fourth time. He carried his Denver Broncos to the Super Bowl, lighting up Bill Belichick’s New England Patriots for 400 passing yards and two touchdowns in the AFC title game.
