Agree with you on his age. Most P5's aren't going to hire a 67 year old coach without a national championship resume. When he left New Mexico, he had been rumored to get picked up by Washington or Oregon State, but they decided to go in a different direction. He also doesn't play the coaching rumor game which means guys like Pete Thamel and others aren't putting his name out there like they did Herman last year. Long's a straight shooter and will give you an answer when asked
Only rumor I can find recently about Long is a return to New Mexico as the Athletic Director, but he denied that one.
