They will have amazing facilities, easy to get to, proximity to great SoCal, Nevada, and Arizona recruiting grounds, and a decent-sized market. They will be able to attract some good opponents.
A great coach could turn them into a powerhouse.
Also, they have relatively-manageable P5 opponents the next 3 years. In 2020, they host California and Arizona State and travel to Iowa State. And, they play in the winnable MWC West division. Just a small handful of playmakers through recruiting or the transfer portal, and UNLV could turn into an MWC front-runner overnight.
