The '99 Wolverines don't look like anything special, looking back. Brady had an average rating, the team didn't run the ball particularly well. Nothing amazing on defense. A lot of close wins basically.
'06 had as good a QB output (Henne), a better running game (Hart), 3-deep at plus WR (Breaston, Manningham, Arrington), better kicker, better return game, and an all-time great run D.
Brady's NFL greatness has nothing to do with a college football game....
