Seeds
The top eight conference teams were eligible for the tournament. Teams were seeded by record within the conference, with a tiebreaker system to seed teams with identical conference records.

Hawaii was initially banned from the postseason for infractions from the previous coaching staff but in the final week of the regular season, Hawaii won their appeal and were reinstated.
