 The Runnin' Rebels, coached by Jerry Tarkanian, entered the season as defending national champions and entered the 1991 NCAA tournament unbeaten, but lost in the national semifinal to eventual champions Duke when Anderson Hunt's desperation three in the final seconds bounced off the backboard and into the hands of a Duke player, Bobby Hurley. 
 They had been the last team to finish the regular season unbeaten before St. Joseph's did it in 2004.
