The San Antonio Spurs have grown worried that Kawhi Leonard's group has an ulterior motive to fray his relationship with the team to get him traded to a larger market like Los Angeles, New York or Philadelphia.

Leonard grew up in the Los Angeles area while his uncle, Dennis Robertson, lives in New Jersey.

"Kawhi really trusts him," one source close to Leonard said of his relationship with Robertson.

In recent weeks National Basketball Players Association president Michele Roberts has offered advice and support to Robertson in managing the situation, according to multiple sources.

According to multiple agents at other firms who met with Robertson in the past few years, he was interested in starting a company similar to LeBron James' marketing company, LRMR, and enlisting their services because he was not a certified player agent.
