look for this to be:
the top 72 teams (by enrollment) go to the new division 1 (whatever they want to call it)
the rest of the teams get re-distributed evenly into the remaining six divisions. since those were roughly 120 per before, these would be about 108 per. If my math is right, d6 would lose the top 12 teams (by enrollment) to d5, d5 loses the top 24, d4 36, d3 48, d2 60, and d1 72. Please correct that if I'm reading it wrong. If true it will really change things the higher up the division ladder you go.
This will then be altered if the competitive balance issue passes.
