He said Aaron is more athletic. Duh, it's hard to think of a QB who isn't more athletic than TB. He also claimed Aaron has a somewhat stronger arm and doesn't have to set his feet and use his body quite the same to make the throw. In other words, Tom Brady has better mechanics.
Not sure if that's really an advantage for Rodgers.
I've always believed that Rodgers, when he's on, is a little more precise with his passes than TB. Clearly, he runs better. I see those as his strengths compared to TB.
I feel TB is better at understanding and manipulating coverages pre-snap as well as his decision making during the play. I give Tom a considerable edge in leadership and drive when the chips are down. Tom also takes better considered risks to pull out a win;
Aaron Rodgers has the best TD/interception ratio of all time (by far) but that can be a bad thing if it means that you don't risk making the play that will win the game.
