The Lakers said Hamblen died in Del Mar. They did not provide a cause of death.
"He was my assistant coach in Chicago, a good friend and great coach. He will be missed,'' Warriors coach Steve Kerr said before Golden State's first preseason game in Oakland.
"He was just a good coach, good guy. I would see him in San Diego summertime. ... He was funny, he was a great basketball mind. I still remember when Frank came to the Bulls we had basically the whole team back and the first day of camp Michael Jordan said, 'Our motivation this year is to get a ring for Frank.' He was new that year. He said, 'Everybody else in this room has a ring but Frank doesn't have one so we're going to get you one this year' and we did -- thanks to me and Michael.'''
Hamblen helped the Lakers win three straight titles from 2000 to 2002 then back-to-back championships in 2009 and 2010. He also was an assistant to Rudy Tomjanovich in between Jackson's stints in Los Angeles and was briefly the head coach after Tomjanovich stepped down in February 2005.
Hamblen spent three seasons as a Bulls assistant, helping them to their final two titles under Jackson in 1997 and 1998.
"Frank Hamblen was a great coach and a good friend," said Lakers coach Luke Walton, who was a rookie player in the organization when Hamblen coached. "He was not only beloved by everyone in the Lakers organization but by those in the NBA community as well."
The Terre Haute, Indiana, native was Milwaukee's top assistant from 1987 to 1996 and worked as assistant coach for the Kansas City/Sacramento Kings (1977-87), Denver Rockets (1972-1977) and San Diego/Houston Rockets (1969-72) during a 42-year coaching career in the NBA and ABA.
