I'm going with 32, I'd like an alignment of two 16-team conferences with either 2 eight-team divisions or 4 four-team divisions in each.
32? thats a lot of teams, maybe in a few decades IMO. I think 20 would be good for now and the foreseeable future, 10 and 10 in each league.
Southeast is a HUGE whole right now.
Chicago seems to be among the slowest to accept soccer, but we have a market big enough for 2 teams if more people start showing their support.
A 2nd team in New York, some more Canada, Milwaukee, St. Louis, Pittsburgh, Minnesota, maybe even Cleveland or Cincinnati...
20 teams now, and capping at 24 until the promotion/relegation converstaion begins --but we're a long ways off from that
As I've always stated, I don't mind it as long as the infrastructure and talent pool can handle it. But we're nowhere near that.
