What's the point of a 4 team league? Why wouldn't they just incorporate some of those IFL teams to have a larger league?
The AFL was on a whole different level, financially. It got to the point where most of the teams folded (or dropped down) because of money issues. I think the AFL technically still has 6 teams, but 2 aren't playing the 2018 season for various reasons.
Personally, I would like to see all of these mid-level/semi-pro leagues consolidate into one big league with regional divisions. It doesn't make a lot of sense for Arizona to be in a league with Iowa/Nebraska teams when there's another league nearby with TX/NM squads. Conversely, the northern teams of that TX/NM league could just as well join up with the Iowa/Nebraska league.
Why not just have a 12-team league with:
Bismarck, Sioux Falls, Omaha, Grand Island, Kansas City, Wichita, Salina, Sioux City, Des Moines, Quad Cities, Green Bay, Cedar Rapids
