U.S. Reed: Razor sharp from halfcourt (1981)
The score: Arkansas 74, Louisville 73 (Midwest Regional second round)
The shot: With five seconds remaining, Reed took an inbounds pass, dribbled up the sideline and heaved in the game-winning shot from just beyond halfcourt to eliminate the defending national champs. Within minutes of each other on this second-round Saturday, St. Joseph's upset top-ranked DePaul, Kansas State's Rolando Blackman sank a last-second shot to upset Oregon State and Reed shocked Louisville.
Danny Ainge: The original mad dash (1981)
The score: BYU 51, Notre Dame 50 (East Regional semifinal)
The shot: Ainge dribbled the length of the court through Notre Dame's full-court defense to score a layup at the buzzer to upset the No. 2-seeded Irish.
Lorenzo Charles: They won it ... on the dunk (1983)
The score: North Carolina State 54, Houston 52 (National championship)
The shot: Dereck Whittenburg's desperation heave from 30 feet fell short, but Charles was there to grab the air ball and dunk home the championship hoop as the Wolfpack stunned the Akeem Olajuwon-Clyde Drexler Cougars.
Keith Smart: One smart shot (1987)
The score: Indiana 74, Syracuse 73 (National Championship)
The shot: Smart was only Indiana's fifth-leading scorer during the season, but he scored 12 of Indiana's final 15 points, include a baseline floater in the closing seconds.
Tate George: Tate's great (1990)
The score: Connecticut 71, Clemson 70 (East Regional semifinals)
The shot: With one second left, George somehow had time to catch a fullcourt pass, come down, square his feet and sink the winning jumper from the deep baseline.
Christian Laettner: The prequel (1990)
The score: Duke 79, Connecticut 78, in OT (East Regional final)
The shot: UConn got a taste of its own medicine, as Laettner inbounded the ball with 2.6 seconds left, got the ball back and sank a leaner from the left side to send Duke to the Final Four.
Christian Laettner: Shot heard 'round the world (1992)
The score: Duke 104, Kentucky 103, in OT (East Regional final)
The shot: Grant Hill inbounds the ball from the far end of the court, and Laettner grabs it at the foul line with two defenders on him, turns and sinks the buzzer beater in one of the most memorable games in Tournament history.
Tyus Edney: Mad dash 2 (1995)
The score: UCLA 75, Missouri 74 (West Regional second round)
The shot: The Bruins' little point guard zipped the length of the court for a buzzer-beating layup. UCLA would go on to win the national title.
Bryce Drew: Just like they drew it up (1998)
The score: Valparaiso 70, Mississippi 69 (Midwest Regional First Round)
The shot: Valpo coach Homer Drew plotted the perfect winning shot for his son to pull off the improbably upset. Jamie Sykes inbounded from the opposite baseline with 2.5 seconds to Bill Jenkins, who touch-passed the ball to Bryce Drew on the right wing, who launched the winning 3-pointer.
Mike Miller: First step to the Final Four (2000)
The score: Florida 69, Butler 68, in OT (East Regional First Round)
The shot: 12th-seeded Butler nearly had the upset, until Miller drove from the left wing and hit a leaner in the lane for the victory. The Gators went on to reach the national title game.
