I do like his physicality and rebounding, though I wonder if he's a good enough athlete for offensive rebounding to translate into a real strength at the college level. I also like his all around game, though I'm not sure it's as good or, again, translatable to college, as some others think.
As for shooting, he was 0 for 3 from 3 in EYBL this year and he was a 64% FT shooter. As far as I can tell, he didn't take a single 3 at Findlay Prep this year. He may end up being a fine shooter, but he hasn't demonstrated that skill so far.
It's not that I don't like Tillman's game, but I think he's had an inflated profile around here, even if his strengths line up with some weaknesses of our past couple teams. On some of our better teams I don't think Tillman would've been a particularly good fit.
