College career Moon was heavily scouted as a high school student and went on to attend
Yonsei University. His time at Yonsei coincided with what is often retrospectively dubbed the "golden era" of domestic college basketball. He and his teammates, as well as their counterparts from traditional athletic rivals
Korea University, enjoyed a level of popularity similar to that of
idol singers and A-list actors/actresses due to their skills and good looks. Together with his Yonsei teammates
Lee Sang-min and
Woo Ji-won and
Korea University's
Hyun Joo-yup and
Chun Hee-chul, among others, they were collectively dubbed "Oppa Troupe" (오빠부대) by the media. As a college player, Moon became known for his accurate shooting and drew comparisons to his older contemporary
shooting guard Hur Jae, despite being a forward.
Professional career In 1994, Moon joined the
Suwon-based
semi-professional team of
Samsung Electronics, which famously scouted him and secured a contract with him before graduation. He enlisted for
mandatory military service in 1995 and was assigned to the . By the time he was discharged in 1997, the
professional league had just been established. Samsung was admitted as a member and Moon and most of his teammates remained with the team. He was an integral part of the Samsung team which won the 2001 KBL Championship. In 2001, Moon signed with Incheon SK Bigs, now
Daegu KOGAS Pegasus, and spent five seasons with the team. During the 2003-04 season,
Ulsan Mobis Automons guard
Woo Ji-won set the record for the most points scored in a single game in the
Korean Basketball League, scoring 70 points against
Changwon LG Sakers in March. On the same day, Moon scored 66 points (22 three-pointers) against
TG Sambo, ranking second behind Woo. The records came under scrutiny from fans and the media due to the statistical impossibility of such records occurring during a regular professional game unless collusion between players and coaches had taken place and the opposing team intentionally failed to play in a usual competitive manner to allow the respective players to achieve their records. As no evidence was ever presented to support the theory, the records still remain in the KBL's record book, but have been described as "shameful" and "embarrassing" by the media and are still regarded as taboo topic by head coaches and players of the respective teams from the two games. == Post-retirement ==
