I agree with most of this, except the part about his role in SL. I think he's needs high usage and should try things. Let's see if that rumored work ethic and between the ears stuff is legit. If so, he should be able to develop those skills over time (may be league average for a 4 by his 2nd or 3rd year).
I agree on the reads. His hoops IQ is high. You can see that on his off the ball movement and how he positions himself to get rebounds on the defensive end of the court. I don't think he'll get many offensive boards though, simply because of where he'll be on the court (in the corner or elsewhere on the perimeter). Defensive rebounds should be a given for a 4. That said, he's not a natural passer. He doesn't lead guys. It's forced. Can he get better? Yes. Will it be dynamic? No.
I don't think it's a full commitment issue. The passing is a processing issue. He wants to do it, but its just unnatural for him right now to do it. As for his handle, those Tatum comparisons from folks, who claimed to have watched him a ton, were head scratchers. Not you--you never did. Others. He exposes the ball too much on his face up--tried to cross the Miami guard (from USF) and got it picked, tried to dribble the ball behind his back while facing up and had it bounce off his foot. Those are unnecessary dribbles. Dude needs more hesitation, more shake, more ball protection, more jump stopping, and popping on his handle. It's going to take time--probably average for a 4 by year 2 or 3. But yhall probably can throw those Jayson Tatum dreams out the window. That's not him.
I'd like to see him defend the 5 spot on defense. If he can defend the 5, he has a Horford type of value. If not, we're looking a 4/3 version of Harrison Barnes/Tobias Harris/Paul Milsap. Good, solid ten year pro.
