Brewer played basketball at Fort Smith Northside High School, leading the Grizzlies to the 1974 Overall Championship and a 30–0 record [1].

Following high school, Brewer attended Westark Community College (now the University of Arkansas at Fort Smith)[2].

He averaged 18.0 points per game while helping the Arkansas Razorbacks reach the Final Four in the 1978 NCAA Men's Division I Basketball Tournament, and was also named to the All-Tournament Team.

Brewer went on to spend eight seasons in the league with six teams—the Trail Blazers, San Antonio Spurs, Cleveland Cavaliers, Golden State Warriors, New Jersey Nets, and Chicago Bulls—and finished his career in 1986 with 5,971 total points (11.9 ppg).

His son, Ronnie Brewer, also played college basketball at the University of Arkansas, and was selected by the Utah Jazz in the first round of the 2006 NBA draft.
