A lot of bad information in this thread.
First...Merlin Olsen didn't attend BYU. He's from Utah State.
Ok, BYU wanted to go independent in football for 2 reasons...ESPN was offering BYU 5 million per home game (4-5 total broadcasts per year) and there were talks between BYU and the Big 12 for BYU to join them within the next 3 years. BYU figured they'd hit up the cash cow as an independent until the Big 12 came calling. BYU was moving all other sports to the WAC. Well, when the MWC big wigs found out about it, they pulled a fast one on BYU and invited 3 WAC teams...Utah State was the first but the Aggies declined because they figured all BYU sports (minus football) were on their way to the WAC. Fresno and Nevada were invited and accepted. When the WAC found out about the invites to Fresno and Nevada, they turned around and invited SDSU and UNLV. No word from either school on what they're doing.
In the meantime, BYU and the MWC are working on a new TV deal similar to what Texas has in the Big 12. Also BYU, the MWC, Comcast, and ESPN are negotiating a deal to let a couple BYU home games be broadcasted on ESPN.
So from the looks of it now, BYU will remain in the MWC, Fresno and Nevada will join the MWC in 2011...the MWC already said they will pay the buyout for both schools that the WAC put in place after Boise left (5 million per team). SDSU and UNLV will most likely stay in the MWC, and next year the MWC will go after a 12th team...rumor right now is either Houston or SMU from C-USA. Thw MWC will then have a championship game and an AQ to a BCS bowl game. That's the plan for now.
