It's a good thing that Lebron is doing this. Say what you want about him, but he's probably the most influential athlete in the nation. So much of the modern NBA is about networking, and if the Spurs are ever going to be a contender in the next seven or so years, Murray recruiting stars to join him is going to be one of the most likely paths. The more you see Lebron and other players boosting him, the more possible it is that someone like Ayton or Lavine or any of the other young future FAs looks at the Spurs and thinks it's a viable location.
