Meh. Cheating makes that highly suspect. Between the spying and deflategate, I can't trust Brady's playoff and Superbowl wins. He may have lost some of those playoff games, costing him Superbowl rings had he not had information that he should not have had.
There's no doubt that he's an amazing QB, but there have been a lot of amazing QBs that don't have scandals casting shadows of doubt on their accomplishments. I will never consider him to be #1. In my opinion, Payton Manning, John Elway, Joe Montana and Aaron Rodgers are all better.
