Drafted 8th in the 1st Rd by the Celtics (for the Clippers), his career was over before it started by beginning it with the Clippers. The Clippers ability to "undevelop" players exceeded all other franchises. Being too raw, he never had a chance. He came into the league a generation too soon. A 3-pt specialist, his lack of physical strengths (6'4, 190, but without strength and quickness), he just couldn't make the transition to the NBA of his time as he was too easily beat defensively while not having point guard skills.
Portland State's home gym, where I watched him play, only seated about 500 people, so every seat was a good one.
He could shoot as well as Steph Curry, and played Defense better than Curry. He had none of Curry's elite passing skills, though. Just the wrong era for him when he reached the NBA.
When he played in the NBA, you could physically attack an Offensive player without getting a foul called. Curry wouldn't have gotten on the court in the late '70's/early '80's, and would have been cut after his 1st contract for the same reasons. Even today, Curry can't handle physical Defense.
He finished in the top 10 in three-point field goals for three consecutive seasons from 1980 through 1982.
The most important moment of Freeman's career: In September 1982, Williams was traded along with John Drew and cash to the Utah Jazz in exchange for Dominique Wilkins, who was drafted by the Jazz and refused to sign.
Williams' scored 81, 71 & 66 points in a game during his Portland State career, totals never matched by anyone against non-Division I opponents in the last 65 years. Freeman was 65 when he died this month.
