If your AD would do his job, and some research, he'd see that attendance isn't everything and can be skewed. For example, let's use Boise State for a comparison. I use them because I would compare them to Marshall. Now, everyone just assumes that their attendance is 40,000-50,000. That's not close. They average around 33,000....and that's for a team that has played (and won) BCS game, bowl games, and nationally ranked in the top 15. And, the city of Boise is about 200,000 strong, while Huntington is maybe 50,000?
So, Boise has 33,000 fans in a city of about 200,000......MU has attendance of about 22,000 in a city of 50,000......do the comparison and see who "should be showing up".
