I've done a similar franchise but based on birthplace/hometown so Dolphins are all Miami born, Rams are LA born, etc. Some teams are from multiple states like Cardinals (Arizona, NMexico, Utah, Colorado). Texas had enough players for three teams (Texans, Cowboys and Broncos). Had to manipulate some positions like QB and K since certain regions had none of these but 90% of players are on their birthplace teams. Definitely have to do it without salary cap because the Dolphins and Rams are loaded. Starting a 32 team franchise to see how it plays out.
