Take the body of in-his-prime Nick Collison, add ten or so pounds of bulk (so, say, 6'10, 7-foot wingspan, 265ish lbs), and give that the strength and motor of someone like Dejuan Blair or Kenneth Faried (maybe not quite Faried-level motor, but you get the point).

That's what he can be like on both ends when healthy.

There's not really a measurement of "physicality" at the combine to compare him to, but the fact that folks often toss out Bill Laimbeer as his best-case NBA ceiling (he won't be that, but even a Diet Coke Bill Laimbeer would still be a lotto pick) should tell you what people think about his physicality and his effort.
