NCAA Tournament Selection Probabilities for Division I - 5/05

By Larry Feldman and Bill Allen

The NCAA Selection Committee now invites 26 teams to the Division I tournament. Thirteen berths are for automatic qualifiers (AQs), which are the champions of their conferences. The remaining 13 are at-large selections from teams not selected as AQs.

Below is a list of teams eligible for AQs followed by a list of teams we believe to have the highest probability of getting selected on an at-large basis.

Here are the 13 automatic qualifiers.

America East: Stony Brook
American Lacrosse Conference: Northwestern
Atlantic 10: Massachusetts
Atlantic Coast: Maryland
Atlantic Sun: Jacksonville
Big East: Syracuse
Big South: High Point
Colonial: Towson
Ivy League: Penn
Metro Atlantic: Canisius
Northeast: Monmouth
Patriot League: Navy
MPSF: Stanford

Next, let's examine the remaining teams for the 13 at-large spots. This may include teams that are still in contention for automatic qualification.

Probabilities of an at-large invitation are based on a team's RPI (ratings percentage index) and SOS (strength of schedule) ranking. Summing the two rankings yields a number that, over the past 10 years, predicts reasonably well whether a team will receive an invitation or be passed up.

Quality wins are not explicitly included in the primary or secondary selection criteria, but they still may play a role in the selection process, and that is why we consider them here. They basically answer the question, who did that team beat? The ranking is based on a scoring system such that if a team beats a top 5, top 10, top 20, or >top 20 team, it earns so many points. And if you lose to the same team, it loses points. The RPI ranking is used to determine whether a team is a top 5 etc., and the higher ranked the team, the greater the points earned (and vice versa for a loss).
