I could see the NFL moving to 36, and doing it fairly easily, as I see 6 markets with NFL capable stadiums. However, there are flaws with each, not factoring in any college teams that use said stadiums. Going east to west (sort of):
Orlando, FL - Camping World Stadium seats 65,000 and hosts multiple college bowl games. The downside is it's proximity to Tampa Bay, as well as sharing the state with Jacksonville and Miami.
Memphis, TN - Liberty Bowl Memorial Stadium seats just over 61,000, and like Orlando, hosts college bowl games. I would be concerned with their proximity to Nashville and the Titans.
St. Louis, MO - so the stadium is there, and was most recently used by the XFL. But the Rams left, citing that the stadium was not at an NFL level. I think St. Louis should get a team, and one with ownership committed to keeping the team in the city. Clearly, with an owner who spent literally billions to build in Los Angeles, he could've made any upgrades he wanted to keep that team in St. Louis.
San Antonio, TX - despite Texas already having the Cowboys and Texans, I think that San Antonio with the Alamodome is a perfect fit. Texas is crazy about football, and San Antonio has enough separation from Dallas and Houston to carve out a solid fan base.
Oakland, CA - The Coliseum is garbage, the Raiders left, and the A's are looking to replace the stadium (but at least want to stay in Oakland). But if they can strike the right deal with the city to get a stadium built (and maybe help the A's with that as well), Oakland's got a strong fan base.
San Diego, CA - As with St. Louis, I don't think the stadium is as bad as the Chargers were making it out to be. Plus, if you can get San Diego more of the modern amenities in a stadium, they're a great site for a Super Bowl, which would be great for the city.
All of these cities would need work to the stadiums (or a completely new one in Oakland). But with stadiums in place, I feel it's more likely that if the NFL chooses to expand domestically (I don't think London or Mexico City is the way to go, but I could buy into Toronto), these cities would be more likely to get an owner willing to fight for stadium upgrades with a city than trying to move to a city like Portland who would need a new stadium entirely, or Oklahoma City where they would need a new stadium or share with nearby OU or OSU.
