I trust Masai.
It's a 20th pick, I don't care of it's a loaded draft or not, by then, the pics are crapshoots. You can get lucky, you can not get lucky.
It's a swing for the fences, but I for one am very excited to see what he can bring on Summer League and also next season.
Keep in mine, 18 years old, at 6'9. He could very well be near 7-feet when done growing, with being able to move and shoot fluidly, that's something you can't teach.
He's got the physical tools, everything else can be taught. He's young, he's raw, but he's a clean sheet. He can be taught, and he can be trained, I'm happy with that.
