A 6-11 center who scored 689 points across 117 games from 1985 to 1988, Lock provided interior depth during the Eddie Sutton era and was part of the 32-4 team that reached the Elite Eight in Sutton's first season. He averaged 10.9 points per game as a senior and was a physical presence in the paint during a period when Kentucky was navigating one of the most difficult transitions in program history.
