Flip and Clayton. Clayton has the makings of the future 6th man level bench playmaker or even starter to help drive the offense and keep things flowing even when the starters are off the floor.
Flip is just too intriguing. When he is on, which admittedly is seldom this season, he has a unique skillset for a big, but he is off way more than on this year, so that is a concern. But it is hard to give up on a guy his size that can basically do it all. If he figures his **** out he could be a real asset and a multi-positional player.
And frankly really none of the others have impressed enough. They are either turning into permanent unrealized potential, or solid, and singularly, one-trick ponies. Sell high where we can. And use that vaunted player development to get the most out of the rest.
