I am a Wyoming alumni and fan who has just retired from Montana to Hawaii and I have been watching/attending WAC and MWC games since the 60's. I have seen a lot of changes since the Arizona Schools left the WAC.
From a Wyo perspective, and I believe most front range schools, an add in Texas is fine. CSU and Air Force really want a Texas presence. TCU was a valuable member in the MWC and is missed. SMU is the preferred add but they are not joining and everyone knows that. UNT and UTSA are who I hear discussed most often. Tulsa and Rice get some mentions. I used to watch Don Haskins bring his great UTEP Basketball teams into Laramie so I have a soft spot for UTEP but I don't hear much support for them.
We get a few ESPN games but most Wyo fans do not miss them as the main TV partner. Yes the exposure was a bit better but ESPN was famous for crappy game starting times. Local attendance suffered as ESPN wanted so many early AM, very late games, and weeknight games. Witness how the MAC sold its soul to ESPN and it has not really helped them. Home crowds are better with CBS and Fox while exposure is Ok. Boise fans might disagree with that but they have more ESPN coverage then the rest of the conference.
MWC always seems to get 5-6 teams in bowl games and I don't think there is a real problem there. So many bowls these days.
I post regularly on the MWC board and UNT is mentioned as an expansion candidate. Frankly, I don't think most MWC fans know much about UNT. Unlike Aresco, Thompson is quiet and works behind the scenes. Their management styles cannot be more different as conference commissioners.
