I actually made that point in an earlier post about it being harder for smaller schools to get games.
I don't know the answer to that on how to ensure everyone gets games. I came up with a random number just because you don't want teams playing a 5 game schedule and trying to get in the playoffs.

Even if they don't do away with regions, which I know they won't, I'd like to see seeding meeting for playoffs. I know from experience that the two of the best teams can come from the same region but have to play an away game in Round 2 because of predetermined brackets.
