Quincy Miller with a 36" vert is pretty good for a guy who's knee health has been questioned.
Same max vert reach as Ezeli and Melo as well.
At 220 pounds already at age 19, I'd say he's got great potential as an offensive minded stretch 4, with versatility at the 3.
He's got some Pierce to his game, and his handle would be a mismatch for most PFs defending him in the high post or perimeter.
