Yeah, he's nowhere near ready offensively. If he was anyone else he obviously stays in college for a few more years.
JJ has him focusing on ball pressure and doesn't care about anything else. He was doing an interview a few days back where he laid out the development plan for Bronny and it's basically to develop him into Lou Dort (JJ's comparison, not mine). So he's told Bronny to get comfortable with ball pressure and being 3 ft in front of his check at all times. If he gets beat, JJ doesn't care, if he fucks up a read, JJ doesn't care.
He's 19 with NBA quick twitch athleticism and a good feel for the game even if the decision making isn't there. If he puts the work in, I think the Lakers turn him into a 3&D backup PG level player. There are worse places to start than with his athleticism and genetics in the hands of the Lakers development staff. A lot of people are overlooking that he was a top recruit in his highschool class (19th in the country) and then had a set back with the heart issue. There's NBA upside there, it just needs a lot of development.
