I hear his son-in-law is getting a job in his administration as a national security advisor. Clearly he is son is qualified since he was a real estate guy.
Who you know is super important in getting a job. However, what you know helps you get results after you get the job. Lebron's friends are in the position they're in because of Lebron, but they've also gotten the right results. Rich Paul is a good agent, look at Eric Bledsoe's contract for example (no Lebron leverage there). Maverick Carter has done a good job building Lebron's brand (I don't think most other business managers can do much better than the $1 Bn in endorsements). Just like those in getting jobs with President Elect Trump because of their relationship, but they also have the right skill set to maximize the opportunity once they got it.
