No. 1: Ed O'Bannon
Unless you're a diehard college basketball fan -- or an even more die-hard NBA fan -- you probably don't remember Ed O'Bannon.
UCLA fans, however, probably remember him as the player who made a miraculous recovery from a knee injury and, in 1995, led the Bruins to their first national championship since the John Wooden era. His college career stats are incredible, averaging 20.4 points and 8.3 boards per game.
The New Jersey Nets, no doubt anticipating similar, if not better, numbers, took O'Bannon with their ninth overall pick in 1995.
This would turn out to be the peak of O'Bannon's NBA career. He played in only 128 games in his two years in the league before that dang knee injury cropped up again. This time there would be no miraculous recovery. This time it signaled the end of a forgettable professional career.
Unless you're a Nets fan, of course. They might never be able to forget the pick wasted on O'Bannon.
