Basketball legend Bill Walton died Monday at the age of 71.

The NBA announced he passed away following a prolonged battle with cancer.

During a 10-year professional career, Walton won a pair of NBA titles and was named the 1977-78 league MVP. He was also included on the NBA's 50th anniversary and 75th anniversary teams.

He was the No. 1 overall pick of the 1974-75 NBA draft by the Portland Trail Blazers following a brilliant collegiate career that saw him win a pair of national titles at UCLA and earn three national player of the year awards.

"Bill Walton was truly one of a kind," NBA Commissioner Adam Silver said in a statement.

He helped redefine the centre position, but his career was cut short by foot injuries.

After averaging 17.1 points and 13.5 rebounds in his first four seasons with the Trail Blazers, he averaged 10.2 points and 8.1 boards in his final six seasons with the Clippers and Celtics.

He led Portland to the 1976-77 NBA title, while being named Finals MVP, and later won a championship with Boston in 1985-86.

He retired after playing just 10 games in the 1986-87 season, and was inducted into the basketball Hall of Fame in 1993.

Following his playing career, Walton became a star broadcaster for decades. He became known for his colourful broadcasting style, where he enthusiastically offered high praise and also blunt criticism.

"What I will remember most about him was his zest for life," Silver said. "He was a regular presence at league events – always upbeat, smiling ear to ear and looking to share his wisdom and warmth. "
