The sports legend was signed by coach Bill Russell to play for the Sonics in 1973 as an undrafted rookie

SEATTLE Supersonics legend Donald ‘Slick’ Watts has died aged 73, his family have announced on social media.

Watts had reportedly been in poor health after suffering a stroke in 2021

His heartbroken son announced his father’s passing, saying: “You did so much for so many of us.

“It was an honor call you pops.”

The NBA icon was signed by coach Bill Russell to play for the Sonics in 1973 as an undrafted rookie.

He was with Seattle for less that five years, but became a fixture known for his broad smile, bald head and crooked headbands.

Watts led the league in steals in the 1975-76 season.

He later played for the New Orleans Jazz and the Houston Rockets but made Seattle his home following his career and frequently attended Sonics events, as well as Washington and Seattle Storm games.

The Storm posted to social media: “We are saddened by the passing of Sonics icon Slick Watts.

“Slick was a champion for the Storm and a beloved member of the Seattle community.”

From Rolling Fork, Mississippi, Watts starred at Grand View Junior College and Xavier of Louisiana before entering the NBA.

In his later years Watts taught physical education in the Seattle School District and ran a basketball academy with his son.

He was named to the Sonics’ 40th anniversary team.

Tributes have poured in for the late star since his passing was announced.

Former NBA center Eldridge Recasner wrote on X: “Slick Watts was my man.

“He was always nice to me and one of the coolest cats you could ever meet.”

And former NBA All-Star Isaiah Thomas said: “RIP to the legend Slick Watts.”
