National Tournament selection and seeding both rely on the same logic.
The logic for ranking teams for the postseason essentially calculates a score for each game on a team's schedule. This game score is determined by the following components:
Once the tournament field has been determined, then the seeding process will begin, using the same evaluation logic. Some teams may be moved slightly in order to avoid same-conference matchups early in the tournament.
Once the National Tournament bids have been handed out, the PostSeason Invitational teams are selected using the same process.
Note: teams must have a minimum of .500 win% to qualify for National Tournament at-large bids and a minimum .425 win% to qualify for the Postseason Invitational.
