LaVar Ball - father of Lakers rookie Lonzo Ball - has criticized the team at its arena after a couple recent games.
The Lakers are trying to shut that down.
Privacy is a valid concern, but I don't think media are pestering other family and friends who don't want to talk.
The Lakers are trying to silence LaVar, and it won't work. He'll just find other place to talk - or ignore the team's policy entirely. Neither he nor the media interviewing him work for the Lakers. The media works more regularly with the Lakers and might want to avoid acrimony, but LaVar doesn't seem like one to quietly accept this. Again though, simply doing interviews elsewhere is easy enough for him.
Most of what LaVar says is harmless, but some of it can affect the team. I doubt we'll hear any less from him as a result of this rule.
