Jackson has been incredible the past 4 or 5 games. Dropping dimes, back-to-the basket game, pick and roll creator, dissecting defenses from the high post, excellent in transition. He and Fultz are 1 and 2 in some order. Jackson certainly looks more locked in at ALL times than Fultz. Fultz is just some kind of virtuoso scoring genius. Both are highly instinctive. Both are gonna be good pros. Jackson has an ugly hitch in his jumper and he's not going to have NBA range. If you can live with that, he might be the better overall player.
After that I'd take Smith, Jr. Then Ball. Then it gets hazy. John Collins is a guy I'd take a flier on later in the first. Pretty weak draft class for bigs. I don't think this draft is as deep as everyone says.
