NCAA Basketball: Top 20 biggest tournament upsets of all time
9. North Carolina State over Houston – 1983
The lowest seed to ever win a National Championship at the time, the No. 6 Wolfpack defeated the Houston Cougars on one of the most iconic buzzer beaters of all time, winning 54-52.
Houston was ranked No. 1 going into the tournament and had won 26 straight games. They were powered by Hakeem Olajuwon and Clyde Drexler, two future NBA Hall of Fame players.
The upset is historically significant, as, at the time, NC State was the first team that did not receive a first round bye to win the tournament. Additionally, they were the first team with 10 losses to win the National Title.
NC State barely made the Big Dance at all, having to win the ACC Tournament to get a bid. They narrowly defeated Wake Forest, North Carolina, and Virginia to earn a spot in the tournament. The Wolfpack overcame numerous late game deficits and early season struggles to become one of the most unexpected championship teams.
The mega upset helped propel the story of Jim Valvano.
