They aren't broke. They have debt. So do other schools. I was commenting about the point the previous fellow made they the "ONLY WAY" UNLV would leave is if the MW didn't pay them the 25 million. They could certainly leave now and pay the exit fee (probably adding to the debt). They could be added to the Big 12 because of all those positives you mentioned. That exit would be free under the new MW guidelines.
The better question is why did they stay in the MW. I believe they were invited to the PAC Who. However, they are in the MW now.
P.S. It was remarkably condescending of you to snark out that they are "stuck" in the MW. They are not paying an exit fee, they will receive some large amount of the monies coming in, and easy travel in a tight regional conference. Certainly not stuck..
