The 1974–75 basketball season was a disappointment to Williams and his team. He managed to score only 9.4 points per game for the Spirits. Williams’ scoring was erratic and he was known for his showmanship rather than his scoring proficiency. He did not play during the following year (1975–76), after which the Spirits of St. Louis were one of two teams, along with the Kentucky Colonels, to fold as a result of the ABA-NBA merger, and Williams ended up without a team despite some interest in retaining him in the league. He was subsequently selected by the Philadelphia 76ers in the ninth round (152nd overall) of the 1976 NBA Draft but the team did not sign him.
