However, in BYU's particular situation its not a big deal. Just schedule more out-of-conference games. They can still schedule the Big-West teams as out of conference games.

this year BYU played 18 conference matches and 8 out-of-conference matches.

Or perhaps the conference schedule will change to 3 matches against each of the other conference members.

I wonder if all of the teams in the conference could schedule 14 non-conference matches if they just had 12 conference matches (2 against each other team).
