League style relegation and promotion. I actually love the idea. You would take the top 64 teams it create a true “D1” with 4 16 team divisions done by geography. At the end of the year, the bottom 2 teams in each division would play a tournament with the top 8 from the new “D2” with 8 open spots in D1 for the 16 teams.
Of course they were only thinking about football with this.
