Sources told Adrian Wojnarowski that the Utah Jazz are close to a five-year contract with the Boston Celtics assistant to become their next head coach.

He'll be the youngest coach in the NBA.

Sources said that the Celtics, Raptors, and Jazz had assistant coaches who met with ownership in Salt Lake.

The Jazz, led by Danny Ainge, conducted an extensive search that included at least 15 candidates. During his eight-season tenure in Utah, which started after he took over a rebuilding team, he had a 372-264 record but did not advance past the Western Conference semifinals in any of the years.

He was an assistant coach for the Celtics and helped Boston advance to the NBA finals.

He started his career as a video assistant for the San Antonio Spurs before being promoted to an assistant coach. He was the head coach of the summer league team in San Antonio.

David Fizdale has agreed to become an associate general manager for the Jazz.

Fizdale will work closely with Ainge and Zanik after 18 years as an NBA head coach and assistant coach.
