Bill Russell is one of the greatest basketball players of all time. He was cut from his junior high school team, and it wasn't until his junior and senior years in high school that his raw athleticism matched his basketball skills. In college he played for the University of San Francisco and won NCAA championships in 1955 and 1956.
He won a gold medal in the 1956 Olympics with team USA before his rookie year in the NBA. In the NBA he played for the Boston Celtics for his entire widely successful career. He's a 11-time NBA champion, 5-time NBA MVP, 12-time All-Star, 11-time All-NBA (3x first team, 8x second team), 4-time rebounding champion.
His no. 6 jersey has been retired by the Boston Celtics, and he's a member of the Naismith Memorial Basketball Hall of Fame, the National Collegiate Basketball Hall of Fame, and the FIBA Hall of Fame.
