Fascinating seeing the mix of optimism and pessimism on display in this thread.
As is usually the case, the truth probably lies somewhere in between.
I tend to be an optimist. Proctor and Mitchell aren't getting the kind of draft buzz most of the one-and-dones have received. There have been a couple of Duke freshmen that went pro anyway, like Duval and Steward. I tend to think those were outliers. Moore, Roach, Williams, Kennard, Hurt, Tre Jones, and others did return under somewhat similar circumstances. So history tells us at least one and maybe both will return. I am optimistic of that, but the history here supports that position.
Filipowski, Lively, and Whitehead are different. They were all top 10 players in their high school class and are consistently in mock drafts. The history suggests they will all go pro. I think Filipowski is the most likely to stay of the three. He is the least athletic of the trio although the most productive in college. He has said things in the past that make it seem like he might be inclined to play another year at Duke. That makes me optimistic he will stay but I understand why others feel different than I do.
Reeves and Schutt seem likely to stay based on historical precedence. Duke has only lost a couple of freshmen to transfer, most notably Brakefield and Coleman. Those two had unique circumstances and were higher-rated recruits coming out of high school. Guys like Goldwire, White, DeLaurier, Baker, O'Connell and others in recent years stayed for at least a sophomore year. The history suggests both Reeves a d Schutt will stay and I am optimistic they will as well.
So the optimists like me are probably overconfident that all but Lively and Whitehead return but I think the pessimists are being too pessimistic for thinking no one will stay. The truth is probably somewhere in between.
