According to Chad Ford:
No one helped themselves more at the combine than Vonleh, despite the fact he didn't do any of the drills there. His measurements (6-foot-9, 6-9.5 in shoes, 7-foot-4.25 wingspan, 9-foot standing reach and the biggest hands of the draft) and his athletic testing numbers (37-inch max vertical jump) make him an elite physical specimen for his position...
The biggest thing that jumps out at you about Vonleh is his ability to shoot the basketball with range. Vonleh shot 48.5 percent from beyond the arc at Indiana this season and it wasn't a fluke. He was a shooter in high school and in workouts the same fluid shooting stroke shined. Vonleh has really unlimited range on his jumper. He had no problem stepping back behind the NBA 3-point line and letting it fly. Usually players with large hands struggle with their jumpers (see Rajon Rondo), but it doesn't appear to be an issue for Vonleh.
The only other big man in the draft that can really shoot like Vonleh is Michigan State'sAdreian Payne. In a league that is hungry for stretch 4s who can provide critical spacing (it was the first thing on Steve Kerr's wish list in Golden State), Vonleh is a unique prospect.
But he's more than a shooter... He has the size, strength, length and leaping ability to finish around the basket. His low-post moves still need a lot of refinement. But his footwork is solid and he has a strong base to create space in the paint.
And then there are those hands. If you watched a lot of game film on Vonleh, you'd see that he could catch just about anything Yogi Ferrell threw his direction. But watching him in drills, you see how remarkable he really is. Vonleh went through a drill where there were two balls placed on each block of the lane. His goal is to grab a ball and dunk it and then move to the other block, bend down, grab the next ball and dunk it, over and over for 10 dunks. Vonleh is the first player I've ever seen do the drill one-handed. He raced from spot to spot, picking up the ball like it was a tennis ball and dunking it. Those hands will be critical to his success in the pros.
