Gerald Eugene Sloan (March 28, 1942 – May 22, 2020) was an American professional basketball player and coach. He played 11 seasons in the National Basketball Association (NBA) before beginning a 30-year coaching career, 23 of which were spent as head coach of the Utah Jazz (1988–2011). NBA commissioner David Stern referred to Sloan as "one of the greatest and most respected coaches in NBA history". Sloan was inducted into the Naismith Memorial Basketball Hall of Fame in 2009.
After playing college basketball with the Evansville Purple Aces, Sloan was selected by the Baltimore Bullets with the fourth overall pick of the 1965 NBA draft. He spent his rookie season with the Bullets before playing the remainder of his career with the Chicago Bulls, retiring due to injuries in 1976. Nicknamed "the Original Bull", he was a two-time NBA All-Star, a six-time member of the All-Defensive Team and the first player to have his number retired by the Bulls. Sloan then became a coach, and had a career regular-season win–loss record of 1,221–803, placing him third all-time in NBA wins at the time he retired.
