leadership, the guy can't stand losing, looks like a douche doing so at times, but his teammates will follow his lead
mechanics, flawless footwork and throwing motion
Pocket presence, he knows how to move within the pocket, resets and fires to the open guy like no other QB.
Doesn't commit turnovers when hit, sans the tuck fumble, the guy gets hit hard but he rarely fumbles.
I rather watch Rodgers play, but Brady is better, IMO.
