My rough assessment in terms of NBA potential:
#1 Mobley
#2 Okoro
(gap)
#3 Stevens
#4 Kabengele
#5 Thomas
#6 Hazer
#7 Hands
#8 Vaudrin
(gap)
#9 Scott
#10 Banks
#11 Bluiett
#12 Ryan
Things get interesting at #5 if we're thinking about potential roster additions. The Cavs will probably sign a young guard for depth, similar to how they have Stevens on the wing and Kabengele in the frontcourt.
#5 Thomas has the inside track having played for the Cavs last season, but unlike Stevens and Kabengele he didn't play well enough to earn a contract for 2021/22.
#6 Hazer and #7 Hands both played overseas, where Hazer enjoyed a breakout season while Hands had a bit of a down year. Both are significantly younger than Thomas, so they could leapfrog Thomas based on potential even if they don't outperform him.
#8 Vaudrin is a bit of a wildcard; he's the best pure PG of the bunch and has great positional size, but doesn't appear to be a great scorer or a great athlete, and he's relatively untested having played in the weak Big South conference.
Players #9-#12 seem to be wing/frontcourt filler guys who don't have any realistic shot at an NBA contract.
