tec sort of handled the answer. The NFL doesn't care who watches their sport as long as they have money. And, after Janet's nipple-slip, the NFL doesn't want to offend anyone. So they go with old rockers. Although the choice of Prince surprised me. I'm assuming they held his mother at gunpoint and said "Do something controversial and she dies."
Jeez, I don't remember. I turn 47 in a couple of days. I think.
