Though Rook would have gained more exposure playing at a higher-level
Division I school such as Kentucky (then coached by
Hall of Famer Adolph Rupp), he instead played for John Rauth's
Indians. As a true freshman in 1961–62, Rook averaged 19.8 points to lead the team in scoring (a feat he would accomplish for all four years). He averaged 22 points as a sophomore the following season. At the conclusion of that year, however, coach Rauth departed and Rook played the final two seasons under
Marvin Speight. Rook averaged 25 points per game as a junior (1963–64) and then 23 as a senior (1964–65). During Rook's career, ASC moved into the
Southland Conference, giving him the opportunity to earn
Southland Conference Player of the Year twice (he was, coincidentally, the recipient of the league's first two awards). ASC advanced to
NCAA Division II regional play twice during his career. Rook's highest-scoring game came during his sophomore season when he scored 43 points against
Louisiana College. He scored 35 or more points in 11 other games, including a 39-point outing against
Lamar University during his senior season. Additionally, he put up those numbers more than 20 years before there was a three-point line in college basketball. Rook estimated that one-third or more of his 816 field goals at ASC would have been three-pointers. Jerry Rook finished his collegiate career as the holder of many Arkansas State University records. Among them, his 2,153 career points, 22.9 points per game average, and 816 field goals made are all still number one. ==Professional==
