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.

Former Seattle Supersonics guard Donald "Slick" Watts has died at 73, his son announced on social media. Watts, an undrafted free agent in 1973, emerged as a fan favorite in the Pacific Northwest due to his stellar play, signature crooked headbands and frequent presence around the Seattle sports scene.

Watts, known for his colorful headbands and his role as an ambassador of Seattle basketball following his NBA career, died Saturday.
