Can't see them pushing out all 3 centers. And replace them with who? There are 13 scholarships and you need big guys in practice. 10 other spots with needs that impact the team more than the center position.
First and foremost need a true pg who can run the show and distribute.
Need a shooting guard who can shoot. I like Starling but he's nearly as limited as Taylor on the offense and can't shoot. He'd be great off the bench.
The 4 spot seems to be fine with Brown and Freeman.
The biggest need behind a pg is the SF spot. Others have mentioned and I agree that we really need a multiple SF who can put the ball on the floor, score and rebound. Easier said than done but it's what we need.
Obviously things are fluid but I see it as Williams and Taylor get the talk and Mintz goes to Europe.
The center is manned by the 3 kids you mention and Brown/Freeman. (Ideally we can find a G6 portal center who can hold on to the ball, set screens, execute a pick and roll and rebound.)
5 spot - McCleod, Brown, Freeman, Cary
4 spot - Brown and Freeman
3 spot - Need a homerun here but it'll be Bell, Moore and Copeland for now
2 spot - Need an upgrade here but it'll be Starling, Copeland, Moore, Cuff
1 spot - Need an Alist pg but for now it'll be Copeland, Starling, Cuff.
Right now the starting 5 might be Brown, Freeman, Bell, Starling and Copeland.
