When I <do> think it's worth noting is that Aaron Rodgers doesn't 'elevate' his game in those situations -- he just basically plays his normal game.
Rodgers is the best QB in football, and he is so good that his team isn't behind very often late in games. But he turns into a different player when he's behind late in a close game. His rating drops almost 12 points, his TD/INT ratio is less than 2.00, and he has almost twice as many sacks as TD.
These numbers are since 2008, when Rodgers entered the league. They include postseason.
