What has happened with traditional MWC basketball powers?

Utah had great rivalries with UTEP, New Mexico, Wyoming and UNLV, and those schools produced some very good basketball teams. The travails of the Utes have been discussed and documented already. New Mexico has not made the NCAA tourney since 2014; UNLV also in 2014; UTEP in 2011; WYO 2005 and then 2015. In my opinion, the Utes are riding a wave of mediocrity. Whether it is at the end of this year or not, the Utes need to catch lightning in a bottle with their next hire.

Basketball in the Intermountain West peaked in 1987-1988.

Wyoming ranked as high as 5
UTEP top 16
BYU ranked as high as 2
UNLV ranked as high as 3
