Seeding

The twelve teams that were invited to the tournament were seeded according to their records:

• Georgetown's first-place finish in the regular season entitled the team to the top seed.
• Louisville and Notre Dame finished the season tied in second, a game behind Georgetown, but Louisville's win over Notre Dame on February 28 gave it the advantage and the second seed and Notre Dame the third seed.^[16]
• Connecticut, two games behind Georgetown, got the fourth seed, and the final first-round bye.
• West Virginia and Marquette both finished four games behind Georgetown in fifth place, but West Virginia's win over Marquette on January 6 granted it the fifth seed and left Marquette with the sixth.^[17]
• Pittsburgh finished five games behind Georgetown and was awarded the seventh seed.
• Villanova and Syracuse both finished six games behind Georgetown and split their games against one another in the regular season.^[18][19] After head-to-head results, the tie-breaking rules of the conference next were based on wins over top conference opponents,^[20] and, although Syracuse beat Georgetown on February 16,^[21] both teams also lost to Georgetown,^[22][23] so Syracuse did not have an advantage over Villanova in games against Georgetown. Tie-breaking then moved to the two teams' results against Connecticut. Villanova's win over Connecticut,^[24] coupled with Syracuse's loss,^[25] gave Villanova the advantage and the eighth seed and Syracuse the ninth seed.
• Cincinnati, at seven games behind Georgetown, received the tenth seed.
• Seton Hall, at eight games behind Georgetown, received the eleventh seed.
• Providence and DePaul finished nine games behind Georgetown, but Providence's win on February 5,^[26] gave the team the twelfth seed, the final position in the tournament.
• The teams finishing below twelfth place after taking the twelfth-seed tiebreaker into account (DePaul, St. John's, South Florida, and Rutgers) did not qualify for the tournament.
