I hope this is true. My info is more general: I have a friend who coaches high school basketball in LA, happens to be Asian-American, and is a huge UCLA booster.
He may be prejudiced in favor of the kid because of his Asian heritage but he says people are really not understanding what a talent Juzang is. His brother, who is five inches shorter, plays for Harvard. My friend, who has watched him many times and was praying he'd go to UCLA, says, "he's not going to blow you away watching a highlight reel. But he's incredibly in control, has remarkable instincts, is a very smart player and is a clutch shooter." He thinks he'll be drafted in the first round some day.
My friend has a good track record -- All the way back to Tayshaun Prince he has been advising me on Southern California high school players, and he has always been on the money. He was also the first person I ever heard of to predict Jeremy Lin could play in the NBA. He says Johnny Juzang will eclipse Lin as the best Asian-American basketball player.
