A 30%-20%-20%-30% split. Sub-divide 1a and and 4a for the playoffs. 32 team brackets. No Wells Fargo Cup or any other other adjustment measures, just ADM's. Use the RPI rating, conference champions get an automatic berth, 2nd place teams get an automatic berth, any remaining wild cards filled in accordingly. No multiple conference champs from split conferences. Determine who qualifies first, then split into 1aa and 1a, then divide east and west. Its not that difficult.
