There's no doubt he belongs in the NBA. The injury thing. Hopefully like you said it was more the Lakers being a bit cautious. Don't like seeing young players get hit by the injury bug so early.
Once fully healed he should spend the summer in the gym working on his shot. But you never know what dumbass scheme Papa Ball has planned.
On his injuries, I think it's a bit of a combo platter. The injuries were real, but I also think that the Lakers were overly cautious and if making the playoffs had been on the line, he'd have played.
As for Papa Ball, it seems like Lonzo isn't really listening to him much anymore. At the least, Papa Ball has been pretty quiet.
