Is he an NFL Fan? Yes.
Is he the everyday NFL Fan? Heck, no.
He's not saving up for 6 months to buy an overpriced ticket, enduring long lines, drunken patrons, a mile walk from his parking spot, thrilled just to be able to see his favorite team w/a pair of binoculars from his seats 1000 feet in the air. If he's frustrated w/his team's performance, he can talk directly to the team. Or better for him, cowardly sit behind a mike w/a national forum to disgust his dipleasure & rouse his audience to feel the same way.
