He can shoot. He's got a hitch in his shooting motion which might not translate well to the NBA, but he was probably the most accurate shooter in the top-5.
Yes, but more. He is a good step back three point shooter. Very good. But he does not seem able to shoot moving to his right side, his shot style is problematic, and he has no mid range game or shot.
To me at least, ball does some things very well. But he has significant holes in other areas. On that front, he reminds me of Simmons.
