The person spoke to The Associated Press on Wednesday night on condition of anonymity because the schools had not made their intentions public. The Mountain West declined to comment on its internal discussions. The conference has already lost five members to the rebuilding Pac-12 over the last two weeks, incuding Utah State earlier this week.
