This makes Head Coach Nick Saban very unhappy.
At a recent press conference Saban expressed his displeasure with the fan base saying that they should stay for the entire game or not bother coming out at all. He was pretty nice about it, but you know it has to bug him if he is going to bring it up without anyone asking him about it. The school has even spent money on a campaign to encourage people to stay for the entire game--Play For Four, Stay For Four.
The only thing I can think of is that the Crimson Tide fans have become complacent....
