Coach Sanchez stated in one of his first interviews that one of his goals was to make UNLV an attractive program for a Power 5 conference notably the Pac-12.
I have no actual inside information concerning a potential move. I just think when you look at the entire picture.
1)Medical School (needed for entrance into Pac-12)
2)Mendenhall Center
3)New baseball Complex
4)Proposed football facility
5)Obvious booster help to football program. UNLV wasn't renting a private jet for the coaches during recruiting on their own dime.
6)University purchased large plot of land.
Its speculation on my part but all of that points towards UNLV making every effort possible to make that move. That is a lot of money and moving parts for a school just trying to keep their head above water.
Most college football writers agree that within 10 years all 5 of the Power Conferences will be either 14 or 16 teams. My guess is 16. I don't think there is a school out there that would want to get left out of that mix. If this did in fact happen it would essentially kill mid-level conferences like the Mountain West, Sun Belt and MAC. The bigger conferences will poach the most attractive schools not affiliated with power conference a bring them in. Boise State to say the Big-12, Northern Illinois to the Big10 Central Florida to the ACC etc...
As for a time frame this again is purely speculation but if you figure we would need a new stadium first, my guess would be we wouldn't see any possible move to the Pac-12 for at least 5-6 years.
I don't think Sanchez has to turn UNLV into some type of dominant school to make this happen. I would bet if he can get UNLV to where they are routinely winning 5-7 games a year it would be enough plus a new stadium.
Again totally speculation on my part.
