He's been on the radar of several (certainly not all) draft-oriented sites for a while now. Some see him as a late first-rounder to mid-second rounder. Here's why I think he's not an obvious first rounder:
- Strength. Getting a good weight reading on him is hard, but it's not a stretch to imagine that he's still south of 200 lbs. Unlike Poku last year, he's not the youngest guy in the draft (he's 20, I think), either. He may be able to get the weight/strength he needs to survive in the NBA, but it's not a given. Since he has basically no mid-range game, he's going to have to prove that he can finish at the rim at least adequately.
-Shot. He has to shoot it to survive, I think, and there are real questions about this. I happen to be optimistic, but there are no guarantees.
-Toughness. I think he plays with a good motor/energy, but that's not the same as saying he has NBA toughness. Given his lack of strength, he has a lot to prove.
-Production. Given the rather mediocre league he plays in, stat lines of just under 10 points, 5 rebounds, .6 blocks a game on 38% from the field aren't setting the scouting world on fire. He'd be drafted much more on potential than production at this point.
(I should say that I buy his height. I also think he will be able to survive on defense if the toughness/strength issues work themselves out. He's quick enough and long enough to be effective. I didn't see any glaring issues from the game I was able to watch of him from a season ago (below). Incidentally, he spent some time guarding our old friend Shelvin Mack in that game. But he's by no means a Kirilenko type defensively. If he succeeds defensively, it's coming first on the perimeter rather than the interior.)
EDIT: Vrenz first checks into the game at about the 27:00 mark. In the second half I think he similarly plays near the end of the third quarter and into much of the fourth.
