My Personal Rankings (Economic & Cultural Factors Considered:
01) Los Angeles-Riverside-Orange County, CA
- Duh
02) Toronto, ON
- Canada and close to Buffalo, but too big and similar to America to ignore
03) Norfolk-Virginia Beach-Newport News, VA-NC
- Big, far from DC and football already embedded deeply in Virginia culture
04) Las Vegas, NV-AZ
- Fastest growing MSA in country, people overblow the gambling stuff
05) Oklahoma City, OK
- Football state but small
06) Salt Lake City-Ogden, UT
- Growing fast, recent success of colleges in state show growing momentum
07) Portland-Salem, OR-WA
- 2nd largest American city on this list but too close to Seattle to be higher
08) Mexico City, MX
- That huge population is tempting but obvious problems/logistical nightmares
09) San Antonio, TX
- Football crazy state, also not in college football crazy city
10) Sacramento-Yolo, CA
- Too close to Bay Area teams despite the large population
