The 5-foot-3-inch Tyrone 'Muggsy' Bogues was the shortest player to play in the NBA, and reports disagree as to whether he could dunk a basketball. His hands were too small to palm it, but he had a reported 44 inch vertical leap, which may have allowed him to dunk.
As of 2014, Anthony Jerome "Spud" Webb was the shortest NBA player to ever win the Slam Dunk Contest. At 5-feet-7-inches, he scored two perfect 50-point scores in the final round. He also trained Nate Robinson, who stood 5 feet 9 inches tall, to win the competition in 2006, 2009 and 2010.
