It's the same argument that has always surrounded Brady. He gets more credit because his fans like to claim his supporting cast is awful, which is not the case.
I can't stand the "circumstantial" shit that causes people to rank 1 player over the other. Let the numbers and the wins speak for themselves, don't handicap a player because he is on a good team. Aaron's numbers at this point in the season are much more impressive than Brady's.
