Although he had a love for baseball, Culpepper committed to play football at UCF as a quarterback. He rewrote virtually all of the school's quarterback records, approximately 30 in all, many held by Darin Slack since 1987. He also set an NCAA record for single-season completion percentage at 73.6%, breaking a 15-year-old mark set by Steve Young (71.3%). This record would stand until Colt McCoy (Texas) finished the 2008 season with a completion percentage of 77.6%. Culpepper accomplished a feat equaled by only two others in NCAA history when he topped the 10,000-yard passing mark and the 1,000-yard rushing mark in his career. He finished his career sixth on the NCAA's all-time total offense list for all divisions with 12,459 yards and was responsible for 108 career touchdowns (84 passing).
