my solution solves the problems stated in yal's arguements,
by reshuffling the divisions every year based on strength you guarantee strong games and weak games.
the divisions would be american and national
the top teams from last year temple usf memphis in a pod, navy, tulsa, houston in a pod
usf, cin, tulane a pod and smu, ecu, uconn in a pod
a top pod and a lower pod create a division.
temple, usf, mem, usf, cin, tulane american div
navy, tulsa, UH, sum, ecu, ucon. national div
all the top teams will play each other, and thier lower pod div mates for 8 games this leaves 3 non conference games
the lower pods play every team in the lower pods plus the top team in thier div.
the kicker is this, best records of the top pods from both div play in the champ game. so temple and navy in this example same as last year.
no need for the relegation concept, the only disadvantage or advantage gained is one game. bottom teams will always play 3 top teams vs 4
this would make for interesting discussion each year.
it's really just a scheduling mechanism
you could also make sure certain teams wind up in the same div for rivalry purposes if they were in different pods ufc, usf. or houston sum, memphis cin. etc...
it could work...
