Before he became a Hall of Fame coach, Jerry Sloan was "the Original Bull" — the tough, floor-burning wing Chicago built its early identity around. He made two All-Star teams and hounded opponents well enough to earn six All-Defensive selections, four of them on the First Team, the kind of nightly resistance box scores never fully captured. His No. 4 became the first jersey the Bulls ever retired. Sloan's playing days ended early because of knee injuries in 1976, but the same grit carried into a coaching life that made him far more famous — most enduringly as the long-serving architect of the Utah Jazz. He entered the Hall of Fame as a coach in 2009. Sloan died in 2020 at 78 after battling Parkinson's disease and Lewy body dementia.
