Westley Sissel Unseld Sr. (March 14, 1946 – June 2, 2020) was an American professional basketball player, coach and executive.

Unseld played college basketball for the Louisville Cardinals and was selected with the second overall pick by the Bullets in the 1968 NBA draft.

[4] Unseld starred for the Seneca High School team that won Kentucky state championships in 1963 and 1964.

[4][5] Unseld played center for the school's freshman team and averaged 35.8 points and 23.6 rebounds over 14 games.

"[11] In his first regular season game, Unseld recorded eight points and 22 rebounds in a 124–116 Baltimore win over the Detroit Pistons.

[9] Unseld was also named to the NBA All-Rookie First Team, and also claimed the Sporting News MVP that year.

[10] First with star ball-handler Earl Monroe and renowned two-way player Gus Johnson, and later with dominant center-turned-power-forward Elvin Hayes and experienced wing Bob Dandridge, Unseld played a key role in the Bullets making four NBA Finals appearances from 1971 to 1979, and won the championship in 1978 over the Seattle SuperSonics, in which he was named the Finals MVP.

[16] Famed for his rebounding, bone-jarring picks and ability to ignite a fast break with his crisp, accurate outlet passes, Unseld made up for his lack of height as a center with brute strength and sheer determination.

Unseld was inducted into the Naismith Memorial Basketball Hall of Fame in 1988, and in 1996, he was named as one of the NBA's 50 Greatest Players of all time.

[19] After Unseld's retirement in 1981, he moved into a front office position with the Bullets, where he served as vice president for six years before being named head coach in 1988.
