Lavar has been right about a lot of stuff... People keep doubting him because he's cocky, but he's broken more news than any professional reporter...
In review he said:
1. Of all the Lakers players Lebron and Lonzo would be best suited playing together. This proved to be true, the Lakers best numbers were put up when those two were on the floor together.
2. Magic was no longer in control and was just the face of the Lakers organization and nothing more. This proved to be true with Magic eventually resigning for this very reason.
3. Luke Walton was the wrong coach for the Lakers and needed to be fired. Ultimately this very fact caused a massive rift in the Lakers organization culminating with the firing of Luke Walton (a good system coach) who made poor personel decisions for the Lakers.
