Hall of Fame NBA coach Dr. Jack Ramsay died Monday in Naples, Fla., having battled cancer for more than a decade and a half.

He was 89. Family members say he died peacefully in his sleep.

Ramsay, also an ESPN analyst, coached 20 years in the NBA, during which he emphasized fitness, selflessness, ball movement and skill -- qualities that carried his Portland Trail Blazers to the 1977 NBA title.

Ramsay has long been an icon in Portland, remembered as much for his distinctive 1970s fashion sense as for the city's only NBA championship.

In his 20 seasons as coach, Ramsay made the playoffs 16 times. He also won a title while serving as general manager of the Philadelphia 76ers in the 1966-67 season. Ramsay was inducted into the Naismith Memorial Basketball Hall of Fame in 1992.

Ramsay attributed a lot of his coaching philosophies to his time in the Navy during World War II, where he worked in underwater demolition, the forerunner of today's Navy Seals. He wrote about it on ESPN.com in 2011.
