Just put Ernie's Heisman in a glass case, have a different Orange alum carry it out of the tunnel right before the player's entrance each game places it on an orange covered table and let the players all touch it on the way onto the field. Done.
The alum who gets to carry it out is like the person who dots the "I" at Ohio State games. Huge honor to be that person.
How about a flyover? Huh, huh? Think about it, since there is a roof, you just pipe in plane noise and show a video of whatever plane you want to. Who doesn't like a military flyover?
