A 6 ft 8 in (2.03 m) small forward, Roberts averaged 16.7 points per game for his four-year career. Through his first three seasons he averaged no more than around 14 points per game. Then, in his senior season in 1991–92, Roberts jumped from an average of 14.5 per game the year before to a nation-leading 28.1 points per game, doubling his output in a single season. He was named the Ohio Valley Conference Men's Basketball Player of the Year and was even selected in the NBA Draft.
Despite being drafted, Roberts never made any teams' final rosters. He eventually became an assistant principal at his old high school, forgoing any professional aspirations. In 1991, Roberts was also selected by the Minnesota Twins in the fourth round (103rd overall) of the Major League Baseball amateur entry draft.
