I found an NBA draft scouting report on report on Adam Miller. Compares him to Wesley Mathews. Says he is "A big (6-4) guard with a strong frame who can make plays on or off the ball"

Well, he is not 6'4". Has average frame and is pretty average athlete.
Cannot create his own shot or finish in traffic at all yet. No pullup. No floater.
Average handle at best. Has no idea how to attack closeouts. No breakdown and pass ability.
Average to below average defender with lack of height and length and average quickness.Did improve that somewhat.
Has not shown he can shoot the three off the dribble at all.
He was actually barely average from three as a spot up guy taking only wide open threes.
I can see him averaging 12-14 ppg if he gets a lot of shots at LSU (and would have done that here), but his game is simply pretty limited.
He has a lot of work to do to be in NBA conversation. Good luck to him, but he just needs to show some game.
