That same argument could be made for all G5 schools actually, not just the MAC. As I said....WMU got to enjoy a nearly undefeated season beating a middling or horrible P5 opponent (we've done that) and some MAC opponents to win a MAC championship (which we haven't done, but definitely attainable). All that it enabled them to do is lose to a big time opponent in an exhibition game. We could do that 4 times a year if we really wanted to...To me that isn't worth essentially starting over from scratch. Losing your coach, half of your recruiting class being gutted, and scrambling to hire the coaching scraps a month before signing day. Nobody on a national stage cares about Hawaii losing to Georgia or NIU losing to FSU now and nobody will care about WMU losing to Wisconsin.
I believe we currently have a coach who has a proven track record in the toughest conference in America. As I said above, I wouldn't sell my soul to lose an exhibition game. If WMU goes back to sucking, I'm betting their fans will feel the same way. Having a program that is enjoyable to watch year after year is worth more than some "magical" year that nobody outside of the fan base will recognize. Most schools will never make an "access bowl". There is approx. a 1.7% chance to make it per school every year. The stars aligned perfectly for WMU to make it. They didn't beat anybody impressive.
It's crazy that nobody wants such a successful coach like Les Miles. 19 FBS vacancies have been filled and not a single one seriously considered Miles. Crazy.
