In his first NBA season, Jones played for the Baltimore Bullets and was named to the NBA All-Rookie Team. The next season, he was traded to the Philadelphia 76ers where he would play for the next six years. Jones and Hal Greer were the starting guards on the 1966-67 76ers team that also featured Chamberlain, Chet Walker, Lucious Jackson and Billy Cunningham. That team went 68-13 during the regular season, then easily won three playoff series in dethroning the eight-time defending NBA champion Boston Celtics.
