Boston Celtics legend K.C. Jones died on Friday at the age of 88.
ESPN's Tim Bontemps first reported the news.
Jones won 12 NBA Championships, 11 in Boston during his career as a player and coach.
As a player, Jones, a teammate at the University of San Francisco with Bill Russell, was a key part of the great Celtics teams of the 60's. Jones would go on to be elected to the Basketball Hall of Fame in 1989.
K.C. was named the head coach of the Celtics for the 1983-84 season, where he would win a championship with the Big 3 against Magic Johnson, Kareem Abdul-Jabbar and the Lakers. Jones would take his team to the Finals four straight seasons, winning another title in 1986 vs the Houston Rockets. Jones is 5th all-time in wins among Celtics coaches, and 1st in winning percentage at .751.
Jones' brother Sam was also a Hall of Fame player for the Celtics in the 50's and 60's.
Bill Russell mourned the death of Jones this afternoon on his Twitter account.
Before today's game against Brooklyn, Celtics Head Coach Brad Stevens said this about Jones: “I got a call today on my way in. I hadn’t spent time with him but I had to stop for a minute. I just think the way he was revered by the players he played with, the people he worked with, other players who played for him — he was special. We’ve had this too much lately with some of our greatest winners and greatest people that have been part of this organization. On a day that people always value their time with family and friends, obviously hampered by the year we’ve all had, it’s a real tough blow. Our condolences are with his family. From our standpoint, you’re talking about a 12-time champion in the NBA, won a couple at San Francisco. Basketball is basketball, but his legacy and character as a person has been something I have heard constantly about since I’ve been here.”
