According to the Denver Post, BYU could announce this week that they will be remaining in the Mountain West Conference. Such a move would seemingly be the result of the Fresno St. and Nevada defections from the WAC to the Mountain West, moves that unstablized the WAC.
Since the WAC exit fee agreement that the then 8 WAC schools agreed to was contingent on BYU joining, it appears that both Nevada and Fresno St. might now be exempt from paying the $5 million exit fee. You can bet that the WAC will try to contest it though.
