IDT 32 major teams is a real possibility. But budget wise 8-10 could sure happen, and the more the player points system is tweaked for AA. Like I said before, you either make the MWS or you play in the AA world at that point is how I'd draw it up.
top 16 in confernce = M
next 16 = AA
anything below = A or whatever
It'll never be perfect no, but on field results can't be manipulated ever.
