I don't think Bronny will be embarrassed in the upcoming season because we have already seen his stats in NCAA, and his performance in the summer league. In other words, we already have a rough idea of his skills and what to expect from him. Anyway, taking into account his stats, I highly doubt JJ will be give him much playing time.
In short he is not NBA ready, and for sure they will be rough against him. I can't imagine other players, even rookie or sophomore trash talking Bronny, as we have found out that he shouldn't be in the league for now, but because he is the son of Lebron, Lakers have no choice but to get him.
So I'm anticipating him like guarding lots of young players like him, like Jalen Green for example of the Houston Rockets. And if Bronny but any chance guard this kid, then there could be some trash talking and it will be good to see what will be the reaction of Bronny.
