A 34 inch vert. is certainly decent. He also plays FB (two sport ath.). There's no doubt, in a general sense, he's athletic. I certainly didn't mean to categorize white guys, if that's what you meant (and I think it's great you call it out). But "athletic" at the ACC level is ... well something else. OB's athletic. I wouldn't say that about HW, or even FH (or did I use that descriptor for GMAC).
For JGIII, there are legitimate questions. I don't think we should jump to the stereotype label. If he wasn't "athletic" in a general (D-1 athlete) sense, he wouldn't even be an SU recruit. The issue is ... is he talented enough athletically to score over size at the rim, to stay in front of ACC guards ... some of whom will be NBA prospects. It's another level. That's what I mean when I question his "athleticism" -- the defensive quickness to check ACC guards, the speed to run transition and the handle to separate and drive the lane. Because if he can't do those things, he'll be one-dimensional, played to shoot and face guarded.
