The UNM athletic program has managed to develop a problem with the reputation of the program
https://www.sandiegouniontribune.com/sports/aztecs/sd-sp-newmexico-20170603-story.html and the football program has contributed including the Bob Davie issues, These followed embarrassing incidents with former coach Mile Locksley and other incidents up to this years public relations disaster with QB Sheriron Jones.
As a result of all this along with the consistent losing overall support for the program has not been strong in terms of fan support or support from many in the university and those who influence the athletic budgets.
MM has his failings including a failure to put enough emphasis on recruiting and an excess of loyalty to certain members of his staff but he is known as a guy who runs a clean program, cares for his athletes and emphasizes academics, maintains discipline in terms of his teams off field conduct. The closest thing he had to a scandal at CU had more to do with timing of his response than failure to respond.
In many ways he might be exactly what they need. He also established a lot of recruiting connections while at CU in the areas the UNM relies on. If he can get a better recruiting staff he could do very well there and they would love him.
