Jerry Sloan, an All-Star player who went on to become the most successful coach in Utah Jazz history, died on Friday following a long battle with Parkinson's disease at the age of 78.
The Jazz announced Sloan's death from complications from Parkinson's disease and Lewy body dementia, which the Basketball Hall of Fame member revealed he was dealing with in 2016.
Sloan coached the Jazz for 23 seasons before resigning during the 2010-11 season and ranks fourth in NBA history with 1,221 victories.
His 1,127 wins with Utah are the second-most of any coach with one franchise, trailing only San Antonio's Gregg Popovich.
"Jerry Sloan will always be synonymous with the Utah Jazz. He will forever be a part of the Utah Jazz organization and we join his family, friends and fans in mourning his loss," the team said in a statement.
"We are so thankful for what he accomplished here in Utah and the decades of dedication, loyalty and tenacity he brought to our franchise."
Led by future Hall of Famers Karl Malone and John Stockton, Sloan's Utah teams were a model of consistency.
He guided the Jazz to playoff appearances for his first 15 seasons after being promoted to head coach following Frank Layden's resignation in December 1988.
The Jazz won 50 or more games 13 times in his tenure, highlighted by back-to-back NBA Finals appearances in 1997 and 1998.
Utah lost to the Michael Jordan-led Chicago Bulls, the team Sloan spent the majority of his playing career with, in both of those Finals trips, with each series ending 4-2.
He also coached the Bulls for three seasons from before joining the Jazz organization as a scout in 1983.
Sloan compiled a 1,127-682 regular-season record with Utah and amassed 96 more wins while leading the Jazz to the playoffs 19 times in total, with seven division titles.
He was honored by the franchise in 2014 with a No. 1,223 banner, representing his combined win total with the Jazz, that currently hangs in the rafters at the team's home venue, Vivint Smart Home Arena.
"Like Stockton and Malone as players, Jerry Sloan epitomized the organization," the Jazz said. "He will be greatly missed.
"We extend our heartfelt condolences to his wife, Tammy, the entire Sloan family and all who knew and loved him."
Sloan also had his No. 4 jersey retired by the Bulls in 1978, the first player in franchise history to receive the honor.
Dubbed "The Original Bull" after being acquired from the Baltimore Bullets prior to Chicago's expansion-year 1966-67 season, the McLeansboro, Illinois native made two All-Star teams during a 10-year run with the Bulls that concluded with his retirement in 1976.
Known for his tenacity and defensive skills, Sloan averaged 14 points, 7.4 rebounds, 2.5 assists and 2.2 steals per game over 11 NBA seasons, and is the only player in league history to average more than seven rebounds and two steals a game.
"Jerry Sloan was 'The Original Bull' whose tenacious defense and nightly hustle on the court represented the franchise and epitomized the city of Chicago," Bulls owner Jerry Reinsdorf said in a statement.
"Jerry was the face of the Bulls organization from its inception through the mid-1970s, and very appropriately, his uniform No. 4 was the first jersey retired by the team.
"A great player and a Hall-of-Fame NBA coach, most importantly, Jerry was a great person. Our sympathies go out to the Sloan family and all his many fans."
Sloan was inducted into the Basketball Hall of Fame in 2009, two years before abruptly resigning 54 games into Utah's 2011-12 season. He rejoined the Jazz as a senior adviser in 2013.
