Larry Johnson and the 1990-91 UNLV Rebels top this list
In 1990, UNLV steamrolled their way to the national title, beating Duke in the championship game by a record 30 points. They returned nearly their entire team the following year, including the 1991 National Player of the Year Larry Johnson.
The 1990-91 Rebels went undefeated in the regular season, annihilating everyone in their path. Their average margin of victory was 27 points. Late in the season, they blew out #2 ranked Arkansas on the road.
The Rebels started the season 34-0, and in the Final Four had a rematch of the previous years' national championship game vs. the Duke Blue Devils. Late in the game, point guard Greg Anthony fouled out while scoring a basket that for all intents and purposes would have put the game away for UNLV. The whistle didn't go the Rebels' way as Anthony was called for a charge, and Vegas was left without a point guard to finish the game.
Needless to say, it did not end well for the No. 1 team on this list. The understandably overconfident Rebels dropped a heartbreaker, 79-77. However, they can take solace in the fact that they won the championship the previous year and still have an unmatched mystique.
