The Pats have guys coming off the bench to score 3 TD's in a playoff game with their all pro tight end out of the game. They still put up 42 points. They also have playmakers all over the Defense. They produce turnovers where we apparently forgot that was part of the rules of football.
Marino and Brady both changed their franchises. The difference in the two is Brady has had great teams which is a big reason he's probably going to his 6th Superbowl. Marino had great receivers, but never had a plus running game and routinely had bad defenses.
