Xers era (1999–2005)
In 1999, Naray Telecom's parent company Sambo Computer took over the naming rights and the team became Wonju Sambo Xers.[1] For a period of time, the Xers were mostly a mid to lower-ranked team and failed to qualify for the play-offs for two consecutive seasons. The team's name also changed several more times while it was under the sponsorship of Sambo Computer or its subsidiaries.
With the drafting of center-forward Kim Joo-sung, the TG Xers were dubbed "Speed TG" for its high-tempo offense helmed by Kim and guard Shin Ki-sung. The team gained a reputation as a well-rounded unit due to a combination of Kim's rebounding and blocking prowess, Shin's speed and shooting accuracy, Hur's experience and versatility and foreign recruit Leon Derricks' physical strength.[7] They finished third in the 2002–03 regular season and reached the finals of the play-offs, where they came up against a Kim Seung-hyun-inspired Daegu Tongyang Orions, the defending champions.[8] TG Xers ultimately emerged as champions, winning four out of six games of the Championship final.
For a period of time, the TG Xers were dubbed the "Yongsan–Chung-Ang Alumni Team" due to a large number of its players being alumni of Yongsan High School and Chung-Ang University. The head coach at that time Chun Chang-jin and several of the team's management staff were also from either Yongsan High School or Chung-Ang University. The term "Yongsan mafia" originated from this era and has been used by the media to refer to hak-yeon (Hangul: 학연, the Korean-language equivalent term of "old boy network") in domestic basketball, even if the aforementioned mentioned names were never contemporaries or actually knew one another from their school days.[9][10]
The following season, the TG Xers finally topped the league table and finished runners-up in the play-offs, losing to Jeonju KCC Egis in the final. However, rumors began circulating among fans about the team's future after news broke in May 2005 that its sponsor's parent company Sambo Computer (known as TriGem Computer in English-language media) was in court receivership due to financial troubles.[11] There were speculations that the team would be folded if no new sponsor could be found.[12] By then, Hur had already retired, and several key players had left for other clubs at the end of the 2004–05 season. The off-season was spent in turmoil and uncertainty, as the coaching staff and players went without pay for up to four months due to Sambo Computer being in receivership.[13][14]
Dongbu Group, via its subsidiary Dongbu Insurance, revealed its intent on acquiring the basketball team from TG Sambo.[15] After protracted negoatiations Dongbu officials confirmed the acquisition on October 7, just weeks before the first game of the 2005–06 season, for an undisclosed price and announced that all remaining players, coaches and staff would be retained.[13][16]
