Every two years it rotates based on record.
Top team over that two year period wont play the bottom team.
Second best doesn't play the second lowest.
..and so on.
It allows teams who have fallen on some times to avoid the top teams, and the top teams the chance to schedule up.
It affords each team a chance to get a second OOC game. As I stated, when Anna added the conference went to a 9 game slate.
Parkway went 8-2 and missed the playoffs even by winning their OOC game so the MAC went to this rotating schedule.
Personally, I think it assisted Ft Recovery to their rise and allowed them to build, and same with NB right now.
Minster folk are too proud to admit it, but I think it helped them as well. Right around the time of this all happening the Cats had some historical bad records, like 0 and 1 win seasons. This easily could have helped them rebuild as quickly as they did.
