He has never shot free throws that bad. With that said he really needs to add a 15 ft jumper to his game. If he could do that then he could get the taller guys who guard him away from the rim and be able to get around them. He has a quick 1st step but he doesn't play over people who are taller than him very well at all. He also needs to learn a hook shot. He is so young he just needs to refine his game. If he wants to play in the NBA he needs to stay for 4 years and work on all of these things.
I agree, he needs that 15 foot jumper...overall needs to improve his offensive skills. He's basically a banger right now, which works for him, but he needs to come back and fine tune his offensive skills
