Artis Gilmore had less than a cup of coffee as a Celtic, ending his career by playing 47 games with Boston. He scored 164 points overall in green, making four starts. The resume that earns him a spot on this list happened long before that time. The 7-foot-2 center first gained notice as a college player, leading Jacksonville to the NCAA championship game against UCLA in 1970. The Dolphins lost but Gilmore was on everyone’s radar. He signed with the ABA Kentucky Colonels and went on to score nearly 25,000 points, bridging both leagues.
