I live in the Southern California area and I've seen Juzang play a couple of times. He's definitely an upgrade over Baker. Baker, while a good player and seemingly a great teammate, was limited athletically at the high div 1 major level. It also didn't help that Cal constantly yanking him, he could never get in a shooting rhythm.
Juzang doesn't wow you, but he does get to his spots and make shots. He isn't ball dominant at all which is great. He is exactly what the team needs, a guy who will stay on the perimeter and you can kick it out to hit the 3. He isn't Tyler Herro, but he will be what we expected Tyler to be. (Tyler completely surpassed that btw). I almost would say that for next year's team, I'd rather have a fundamentally sound guy like Juzang to stretch the floor than some athletic freak like Hami because that's what we need. His game fits in perfectly with the way basketball is going and the importance of shooting/stretching the floor. I'll also add that Juzang plays in an area where the competition is much better than Tyler in high school. Juzang can definitely contribute as a freshman and someone who could potentially be a really good player by his Jr. year which I doubt he stays that long. I can see him good for 6-8ppg as a freshman.
Also, I have no inside information obv. I never paid much attention to him as a recruit because I always got the feeling he'd end up at a West Coast school like UCLA/USC. So. Cal kids tend to do that. Juzang's older brother is a pretty decent player at Harvard though so there's that. I was hoping a kid that Kentucky would get in on as a grad transfer was Max Hazzard. He played for my alma mater UC Irvine. Really good player and lit up the NCAA tournament. But I think he had a lot of connections to Arizona so that was a done deal before anyone had a chance.
