[2][3] He was one of the stand-outs at his high school and was recruited by Yonsei University, where he would be joined by his future Anyang KGC teammate and best friend Yang Hee-jong.

In the 2005 MBC Cup, Kim scored 20 points during the final against Chung-Ang University as Yonsei won the competition for a fourth consecutive time.

[8] In a surprise move, Seoul SK Knights decided to trade him and another player to Anyang KT&G Kites for former MVP Joo Hee-jung at the end of the 2008–09 season.

[12][13] His signing was meant to be part of a major squad rebuilding project by coach Hur Jae but did not play for his new team for the first round of the season due to his participation in both the 2014 FIBA World Cup and Asian Games.

Although no longer an automatic starter due to his age and physical condition, his experience was highly valued and he served as a mentor to the younger guards in the team.

He made guest appearances on several variety programs and started a Naver blog, in which he posts about recent developments in both college basketball and the KBL.
