Admittedly, the visit may be a matter of convenience because his mom will already be in Knoxville for the Hall Of Fame ceremonies. But still, he's visiting and for your 12th or 13th scholarship, you can do a lot worse than a kid who won the A-Sun ROY award, led his team in scoring averaging 14.5 ppg, and shot 38% from 3 as a 6-9 SF.
He's not a great defender, but he played for a team that doesn't emphasize defense, either. Central Arkansas gave up 78.2 ppg and no one on that team had a positive defensive box +/- nor a defensive rating below 107. Just as an example, everyone except JP Estrella was at 100, or below, for Tennessee last year. With 3 years of eligibility plus a redshirt, he can be taught to be a better defender by a staff that emphasizes defense.
On the rebounding front, he only averaged 3.7 rpg, but our main 3s (SG/SF) only averaged 3.7 (Vescovi) and and 4.9 (Knecht). Again, you can teach a kid to be a better rebounder. And as his teams leading scorer, it isn't unreasonable for his rebounding to be down given he was the primary shooter/scorer and played on the perimeter. You can't just look at his height and say, oh he should aversge at least X number of rebounds. His position and offensive role matters. At Tennessee, he will be more free to crash the boards. The hope is that he'd add 20-25 lbs and be able to contribute more in that area with less offensive responsibility, added strength, and better coaching.
