19. Oscar Robertson, Cincinnati
The Big O always did put up some pretty huge numbers. Oscar Robertson averaged 34 points, 15 rebounds, and 7 assists per game during his Cincinnati career. He won multiple national player of the year awards all three seasons at Cincy and was so good they named one such player of the year awards after him once he had left for the NBA.
Robertson piled up the numbers in March too. His 56 points are the third highest ever in a tournament game, and he also compiled four tournament triple doubles. To properly appreciate that, you should know that only Magic Johnson and Draymond Green even have two triple doubles in March Madness history.
