This marked the final conference tournament played under the league's original 8-team format. TCU joined the Mountain West in the 2005–06 athletic year. From that point on, the tournament adopted a first round play-in game, pitting the 8th and 9th place teams against each other for the right to play the regular season MWC champion in the tournament quarterfinals.
