This versatility is something that can surely be harnessed in the NBA, which is heavily oriented around exploiting mismatches at different positions. With Miller's ability to create his own shot on the perimeter, make 3-pointers or utilize his superior size in the paint, he could be a very difficult player to game-plan against on a nightly basis, especially considering his solid passing skills.
As a shooter, Miller has been very good for the most part, knocking down a solid 43% of his jumpers so far this season, including an impressive 41% from 3-point range, despite a low, unorthodox release, dipping the ball below his waist and shooting it from above his chest. He's much more effective shooting the ball with his feet set at this stage, as his percentages take a dip when he forced to take a shot under duress, particularly off the dribble.
Quickening the speed of his release would allow him to fully utilize his excellent size and make him much more dangerous from the perimeter considering his terrific touch and instincts as a shot-maker.
Inside the paint, Miller has excellent potential, as he is able to get his shot off almost whenever he wants against collegiate-sized (or even most NBA-sized) small forwards. Despite not always having the strength to establish great position, he can simply rise up off either shoulder and throw the ball in the basket in a variety of ways, be it with jump-hooks, floaters and turnaround jumpers, using the glass, and even when off-balance. As he continues to get stronger and learns to become more physical with opponents, this is a part of his game that could really blossom.
Miller's most impressive attribute might be his ability to create shots off the dribble. He doesn't have the most explosive first step, but he has outstanding scoring instincts, doing a nice job utilizing shot fakes and showing terrific ball-handling skills for a player at 6-9. He's able to put the ball on the floor with either hand and utilize crossovers, hesitations, spin moves, jukes, and step-back dribbles to create separation to get his shot off, with superb body control and very polished footwork.
Watching him grab a rebound and take the ball coast to coast, weaving his way fluidly in and out of traffic, really hammers home how unique his skill-level is at his size.
