Notre Dame's stare down in the tunnel was actually very effective against undisciplined teams in the 80's like Miami & FSU. Notre Dame's tactics can cause players on most college teams to lose focus on the big picture and instead focus on playing head games.
The same thing worked in the UGA-UF game this year. UF could have easily won the game, but their players couldn't resist trying to fight the UGA players. Much of it was retaliation, but it still took them out of their game.
