An argument could be made that Jalen Smith will be as effective a player in the NBA as Myles Turner. He's not as long and imposing defensively, but he moves a bit better and has better offensive stats. His advanced stats are also right there with Paul Reed. He needs to add strength and flexibility in his lower body, and I think his defense would improve as a result. He's only 20 though, so you'd expect he should be able to do it with a year or two of NBA conditioning.
He's more of a face-up guy than a post-up guy, and could end up being better in the NBA than in college. He's got the jumper and some touch on floaters. He also runs the floor really well. He's not a good passer, but could learn with some reps in Quin's system. Both Smith and Paul Reed are 6'9" - 6'10" with a 7'1.5" wingspan, and they should end up around 230 lbs. Reed is the more versatile defender, and Smith is the more natural shooter.
