If the MLS is genuinely successful enough to hit and maintain ~22-24 teams, I hope they actually take a little bit of time to develop a true MLS-managed minor league and implement a promotion/relegation system, instead of just growing the MLS itself to 25+.
I've always heard it wasn't possible since the teams have to pay so much to get in and they wouldn't tolerate the loss in revenue from being relegated.
But maybe it could work if each FC also owned their minor-league equivalent? IDK.
I just want US Soccer to sort it out
