Grayson was a three-year starter at forward for the Crusaders, competing on teams which posted a 49-28 record. He served as captain during his senior year. Known chiefly for his prowess on defense, Grayson was always called upon to guard the opponent’s top scorer, including the likes of Johnny Neumann of Ole Miss and the legendary Julius Erving of UMass. Grayson was also a presense on the boards, as he grabbed 22 rebounds (and scored 35 points) in an HC victory over Georgetown in 1971. It was the first 20+ rebounding game for a Crusader since 1956. An accurate shooter, he also led the Crusaders in field goal shooting (.459) during his sophomore year. Grayson was selected as the Crusader of the Year in 1972.
