I would be okay with the AAC, if:
- college football instituted the ability to host conference championship semifinals, with conference scheduling deregulation
- the AAC owned and promoted the Las Vegas Bowl to quasi (or actual) NY7 status
- all sports invitation with additional western members
- BYU was able to pick its new western members for AAC divisional realignment
- BYU was still able to play Utah, Boise St., and Utah St. every year in football and Gonzaga, Utah, and Utah St. every year in basketball.
I would propose three 6-team divisions, basically adding a new western division (an re-designating a "central" division). Ideally, I would want to include Boise St., Utah St., Hawaii, SDSU, and UNLV in our football division, for the rivalries and geography for fans and recruiting.
Conference championship semifinals includes three division winners and one wild card, hosted at the home fields of the top two division winners. Conference championship title game in the new NFL stadium in Las Vegas? Conference champion gets automatic bid to the Las Vegas NY7 bowl game, played around New Year's.
BYU gets Boise St., Utah St., Hawaii, SDSU, and UNLV on the schedule every year, and then rotates three games through the other 12 schools - playing everyone in the conference once in 4 years. This allows BYU to play conference games against familiar foes and rivals, but also to travel to all corners of the country. I would suggest that BYU still try to play 3 or 4 P5 opponents per year, may be even up to 5 when we play at Hawaii. Using the Hawaii exemption, the AAC could dominate Week 0 and the kickoff of the college football season with a bunch of fun games.
Similar structure for Olympic sports, especially basketball, except you play home-away with everyone in your division and then rotate through the rest of the conference, limiting cross-division travel to only two 2-game road trips. The conference tournament could rotate among (1) Las Vegas; (2) New Orleans/Dallas/Memphis; and (3) Philly/New York.
BYU's basketball division would include Gonzaga, Utah St., Boise St., SDSU, and UNLV. Again, great games on the home and road schedule and then play the occasional Cincinnati, UConn, Memphis, Wichita St., Temple, Houston, SMU, etc. That would be a huge upgrade for basketball.
