Well it is unfair to ask since Tom is still playing thank God. If he wins another Superbowl or two, Brady will go down as the best player in the history of football. Time will tell.
Two Super Bowl seasons tainted with cheating is the asterisk that will be forever beside Brady. Montana has nothing like that in his career.
If Brady wins another, he will be the quarterback with the most Super Bowl wins. He will also be the quarterback of the NFL team that holds the record for the most fines for cheating in games.
Actually, it depends upon his protection! He does seem to get a bit confused if pressured. I do like the quick passes though as they planned it to prevent unwanted pressure.
Good quarterback but still has problems if facing a good defensive rush. His Achilles heel. Fortunately, his offensive line has kept him out of trouble and so he is the hero.
