Sinclair made it onto the basketball practice court during open tryouts as an unrecruited 6-foot-5, 175-pound center, based on a dare from Lon Smith, whom he played against in high school. He made the practice team and practiced every day, hoping to eventually make the travel team or at least the dress-out list for home games.
Neither of those events happened. So the previous head coach, Cal Irvin, became the athletics director the following year. The assistant coach, Warren Reynolds, became the head coach, and Sinclair grew to be a 6-8 center. Sinclair made the team but mostly rode the bench, getting in the game predominately when A&T was winning or losing by a large margin.Â
The following year, Reynolds called my name (or something close to it) during the middle of a game. Those warm-ups came off of me with lightning speed. Now that I had a little taste of playing time, my main goal was never to ride the pine again. Sinclair accomplished his goal, and it didn't hurt that he grew to 6-10, 220 pounds. Even if the basketball stars had not aligned appropriately, my journey would have been different. I'm grateful they aligned correctly!!Â
Sinclair's accomplishments included Black College All-American (1975-76), first-team All-MEAC (1975-76), and he made the MEAC all-tournament team. The Aggies played in the NIT at Madison Square Garden that same season. He also led the nation in rebounding. The Aggies won three MEAC regular-season and tournament titles during his time there and made the ECAC tournament (1972).Â
In 1973, the Aggies won the 1973 Charlotte Tip-Off, where Sinclair made the all-tournament team. Two years later, the Aggies won the Aggie Holiday Classic, where Sinclair also earned all-tournament honors. In addition, he was named the team's most-improved player in 1974-75. The following season he earned team MVP.Â
In addition, he earned team co-captain recognition for two seasons. In 2020, he made the MEAC's 50 greatest men's basketball players list during the conference's 50th anniversary. Academically, he made the Dean's list in 1972, '74 and '75.Â
Sinclair is happily married to Lizabeth (Libby) Goss. His children are Ashli Brooke Colbert – daughter; Trent Cullen Goss – stepson, Shaun Sinclair Colbert – son (deceased).Â
