speculations on positions, now that you mention it, it looks like Aytes is working hard on expanding his shooting range, perhaps to play some SF.
Worthington will likely be used in the 5 fouls and out enforcer role. There is a useful place for him on the team but don't see him as the #2 center unless he gets a lot better in the coming months. Also, Luke is a good locker room man.
In high school Neilson was primarily a defensive specialist at center and i have high hopes that he can protect the rim as a back up to CK. Regardless, i see Austin as the underrated backup 5 and probably the starter at PF, with Austin, Aytes, and Neilson joining Corbin as those who will earn the big minutes at C and PF.
Back up to Haws and back up PG are wide open right now.
update: If Aytes is a near certain starter as mates say, would guess that Austin gets the nod at C, with Kaufusi getting bigger minutes over time.
