[citation needed] Williamson went on to team up with Scott and Davis at New Mexico State University where he averaged 27 points per game within 2 years.

Before signing with the ABA Nets, he had been eligible for the NBA draft that year, being selected by the Atlanta Hawks in the 6th round with the 96th pick, but didn't make the cut for their roster.

By this time Williamson had largely declined as a player despite being only 29 years old and wouldn't return to the NBA after that season due to contract disagreements in free agency and not maintaining a healthy weight to play.

[2] In 1982, he would play for the CBA Las Vegas Silvers in an attempt to get recruited back into the NBA but never received any offers.

Williamson still holds Nets team records in various categories, including most free throw attempts in a game, with 24 (since tied by Vince Carter and Devin Harris).

After professional basketball, Williamson would end up working in a juvenile detention center back in his hometown of New Haven, Connecticut.
