I've watched about 5-6 of Avdija's games this year. I truthfully feel that he has benefitted more than anyone from the disappointing seasons in the NCAA. I don't think many have actually watched his film from this season, as pretty much everyone has him ranked in the same 5-8 range with no variation whatsoever.
I've truthfully been disappointed with Avdija as well, specifically on the defensive end. I see many tout him as a plus defender, but I don't see him as that even for Maccabi, where there's a much lesser athleticism gap of course. He is extremely foul prone, and not in a way that he's flying around and contesting shots. He just doesn't have a great sense of where his body is I don't think. He undercuts players regularly, and moves into guys driving on him 1 on 1. I've not been wowed by his instincts either, which I've seen touted as well. He's been average at best off ball in the games I've watched. He's not too much of a deterrence at the rim either, despite the size. I just don't really know who he defends in the NBA at an above average level.
Offensively I think I'm more optimistic on his jumper than his numbers indicate. His role with Maccabi really puts him at a disadvantage on this end. He essentially spots up in the corner all game and crashes the boards. But you can definitely see the passing ability in grab & go situations. The question is how useful is that skill at his size if he doesn't shoot it? In the halfcourt, can he break down the defense in any way in order to create the opportunity to show off his passing ability? That to me is the biggest question, but I doubt I'll feel comfortable with an answer to that come draft time.
Also he gets credit for the confidence/energy he plays with. There is at least one instance per game where he shows negative emotions in one way or another - whether frustrated with officiating, teammates, himself, etc. I'm not reading too much into it right now, but I still think it's worth pointing out.
Factoring in the defensive concerns that I have and the lack of shooting right now, I am definitely lower on him than that 5-8 range. It's still a small sample size, so my opinion could still change quite a bit.
