Autographs of Jack Sikma
Jack Wayne Sikma (born November 14, 1955) is an American former professional basketball center. He was a seven-time NBA All-Star with the Seattle SuperSonics, who drafted him in the first round with the eighth overall pick of the 1977 NBA draft. In 1979, he won an NBA championship with Seattle. Sikma finished his playing career with the Milwaukee Bucks. He was elected to the Naismith Basketball Hall of Fame in 2019.
He was known for his trademark reverse pivot and step back behind-the-head jumper, coined as the "Sikma move", along with his distinctive blond hair during his playing days, which he wore in a pageboy early in his career and in a curly style later on. During his thirteen-year career, he reached the playoffs eleven times and anomalously established himself as an accurate-shooting center. His style of play would become significantly influential for centers at both the amateur and professional levels. Sikma scored 17,287 points in his NBA career.
Sikma was born in Kankakee, Illinois to Grace and Clarence Sikma and attended St. Anne High School in St. Anne, Illinois. He lived in rural Wichert, Illinois growing up. Sikma was a guard his first three years of high school, before a growth spurt had him at 6'10" going into his senior season. Nicknamed "the Wichert Wonder," Sikma led the St. Anne High School Cardinals to a fourth-place finish in the 1974 Illinois High School Association (IHSA) Class A boys basketball tournament, scoring 100 points in his four tournament games.
