He's better than Duncan Robinson, but they have almost identical splits of two and three-point attempts. As far as I can tell his shots come off of catch and shoot attempts or drives at closeouts. He plays out of the PNR game, but is almost always looking to pass (more out of Pitt's DHO offense). He does seem to have really good passing ability which is impressive.
The one area he does have an obvious advantage is defensively and on the glass with his length and athleticism over Duncan.
Offensively though, I think they'd play very similar roles.
As far as scoring in all three levels, I assume you mean at the rim, in the midrange and from three. He attempted 13% of his shots in the mid-range and shot 33% and 18% of FGA at the rim and shot 54%. Those are pretty much numbers for a guy who is primarily a catch-and-shoot guy (2/3 of his attempts were threes & 2/3 of attempts were catch and shoot).
For comparison... a guy like Irvin attempted 25% of shots at the rim, 39% in mid-range and 36% from three. That's kind of the split I would call a three-level scorer and Irvin was labeled fairly one-dimensional by many.
