LeBron James is establishing some boundaries when it comes to Bronny ... making it crystal clear he's not going to speak for his son -- telling reporters if they want to know anything about the Lakers rookie's experience, they can ask him directly.
The four-time NBA champion explained his stance during media availability on Monday ... saying Bronny's fully capable of taking his own questions.
"He's a grown man, ask him how he's handling it," LeBron said of the Bronny-related question.
