Originally thought 70,000+. But I forgot about this being a televised game. Change my original answer to 80,000+.
Keep in mind that WE are the ones that started all of this craze about the spring game attendance. ESPN isn't coming to our spring game to promote the game itself. They're coming on the platform that we pack the house for this game and they're interested BECAUSE of that. So to have ESPN bring their crew down to T-Town with all the publicity surrounding our spring games and knowing how we as Bama fans have bragged about it. To NOT pack it out WOULD be embarrassing in my opinion because that is what the announcers are going to be talking about the most leading up to the actual game.
