Best NBA Vols is a sadly short list.
1) BK
2) Ellis
3) Houston
4) Harris
5) Richardson
6) Watson
7) Boerwinkle
8) Grunfeld
9) Johnson
Grant has opportunity to speed up the list, 7-8-9 never did a lot notable. They just stuck around and had some 10-12ppg 4-8 rebounds per game type seasons.
It's way to early to say he's better than Harris or even Richardson and probably Watson. Grant has started less than 40 games in his 3 year career to date.
I'd love to see he, Keon, Jaden and KC become players that get a lot of run and make a big impact. If they all became Tobias level players it would be amazing.
