This for the moment gives USL Championship 35 teams for 2021. It's possible that both OKC Energy and FC Tulsa will move to the East, especially if a full season is played, and without any restrictions.
If the 2020 format continues next year, I could see this happening:
A - Tacoma, Portland, Sacramento, Oakland, Reno
B - Las Vegas, Los Angeles, San Diego, Orange County
C - Phoenix, Real Monarchs, New Mexico, Colorado Springs
D - El Paso, Austin, Rio Grande Valley, San Antonio
E - Oklahoma City, Tulsa, Kansas City, Memphis
F - Louisville, Indy Eleven, Birmingham, Charlotte, North Carolina
G - Hartford, Philadelphia, New York, Loudon, Pittsburgh
H - Tampa Bay, Atlanta, Miami, Charleston
