Yes, technically the New Mexico Lobos can win the division as their final four games are intra-division games but they include Boise State, Utah State, Colorado State and Air Force. In realistic Mountain Division news, Utah State is still in the drivers seat to win the division even after their loss to San Diego State as they own the tiebreaker over Boise State.
Utah State needs to win out to represent the Mountain Division in the title game but any slip up will allow Boise State or Air Force to take that spot. Boise State bounced back with a win over Wyoming to stay in the race.
