The SuperSonics played their home games mainly at the Seattle Center Coliseum, the Kingdome during eight seasons, and the Tacoma Dome for one season while the Coliseum was being remodeled and later renamed KeyArena.
Since then 257 players have appeared in at least one game for the franchise.
Nine players were inducted in the Naismith Memorial Basketball Hall of Fame, Ray Allen, Patrick Ewing, Spencer Haywood, Šarūnas Marčiulionis, Gary Payton, David Thompson, who played no more than two seasons with the Sonics, and Dennis Johnson, Jack Sikma, and Lenny Wilkens, who were part of the 1979 Championship team, with the former as player and the latter as coach.
Wilkens was also inducted to the Hall of Fame as coach, having the longest career-span of any coach in NBA history.
