I'm not a fan of this in any way. I like how it operates now. The coaches already have the option of playing a match tb if the overall team match is decided. I believe they have liberty to play match tb's in non-conference matches already if both coaches agree.
If anything, I'd change doubles to the pro format of no-ad scoring with a match tb when splits happen. But, the 8-game pro sets are working fine. Nothing is broken so it would be a shame to try to "fix" the college game.
