While touring China to promote the shoe company Anta, Kevin Garnett participated in an interview with Chinese website Hupu.com, and was asked about his future in the NBA. According to HoopsHype's translation, Garnett indicated that he intends to finish his playing career with the Celtics.
While it's hard to determine the exact context of Garnett's comments when they've been translated from English to Chinese and back to English, it shouldn't come as a surprise that he intends to finish his career in Boston. The 36-year-old signed a three-year deal this summer to remain a Celtic, and though there's no guarantee he'll retire at age 39, it sounded like retirement was an option he was considering as early as this offseason.
If Garnett does play past his current contract, I still wouldn't expect him to leave Boston as long as Doc Rivers continues to coach the team. Former teammates Kendrick Perkins and Sam Cassell both suggested earlier this summer that they couldn't picture KG playing for any coach except Doc.
