Sloan is 17 wins behind Pat Riley for third all-time on the NBA coaching victories list, and has compiled 1,193 victories during 26 seasons guiding Chicago and Utah.
He officially signed on Aug. 5 to coach the Jazz this season. Sloan has annually made a decision about each upcoming campaign by late December, and then used the offseason to evaluate his desire about returning to the team.
Utah (3-3) is engaged in its biggest rebuilding year since 2005-06, when the team finished 41-41 after acquiring point guard Deron Williams with the No. 3 overall selection in the 2005 NBA Draft. The Jazz lost key players Carlos Boozer, Wesley Matthews and Kyle Korver over the summer, while the additions of veteran Al Jefferson and rookies Gordon Hayward and Jeremy Evans have initially created a team in search of a new identity.
Messages left for Jazz general manager Kevin O' Connor and team president Randy Rigby about Sloan's extension were not immediately returned.
