The Blue Devils had ended the 1990 season with a record-setting 30-point loss to the UNLV Runnin' Rebels in the national championship game (103–73). After losing seniors Phil Henderson, Alaa Abdelnaby, and Robert Brickey to graduation, Duke welcomed a new addition to the team, freshman Grant Hill.

With junior Christian Laettner and sophomore Bobby Hurley leading the way, Duke placed third at the Preseason NIT (behind Arizona and Arkansas). The Blue Devils went on to compile a 25–6 regular season record, including a perfect 16–0 mark at home. Scoring victories in both rivalry matches against North Carolina and sporting an 11–3 conference record, Duke also captured their 9th regular-season championship in school history.

Duke entered the ACC tournament as a No. 1 seed, but stumbled in the ACC title game against North Carolina by a score of 96–74, even though the Blue Devils had defeated the Tar Heels twice during the regular season. As a result, North Carolina received the top seed in the East Regional, leaving Duke with a No. 2 seed in the Midwest Regional of the NCAA tournament.

Duke however tore through the Midwest Regional, defeating St. John's to join UNLV, Kansas, and rival North Carolina in the Final Four in Indianapolis. Entering the semifinal game against UNLV, the Blue Devils were facing an undefeated and top-ranked Runnin' Rebels squad that boasted a 45-game winning streak and featured National Player of the Year Larry Johnson. In one of the biggest upsets in Final Four history, however, Duke got its revenge from a year ago by a score of 79–77 after Laettner hit two free throws with 12 seconds remaining and UNLV guard Anderson Hunt missed a three-point attempt at the end-of-game buzzer.^[1][2]

An all-ACC, Duke vs. UNC title game was averted when Roy Williams coached his Kansas Jayhawks team to victory over his mentor Dean Smith and his Tar Heels squad. In what would become the first of many matchups between Williams (later head coach at North Carolina until his retirement in 2021) and Mike Krzyzewski, Duke finally claimed its first national championship by a score of 72–65. Laettner was named NCAA basketball tournament Most Outstanding Player.
