I don't know. Duke could be thin or overloaded on the perimeter/wings heading into 2021.
Jordan Goldwire and Alex O'Connell will be seniors next year.
Joey Baker appears to be on a 4-year college track, so he will be in play as a wing.
I am assuming that Wendell Moore, Jr. will be a sophomore next year but hoping for a big year from him. He could be off to the NBA or could be a 3- or 4-year guy. It's tough to tell with him as he has obvious skills but a few critical limitations right now. If he figures out how to improve on a few things, like the handle and jumper, he could be very good.
Jeremy Roach and DJ Steward are both 5-star recruits and McDonald's All-Americans. I assume every one of those types of players has an eye on being a one-and-done even if the freshman season doesn't pan out that way. It is possible that Steward could go pro after his freshman season.
If Goldwire, AOC, Moore, and Steward all depart after next year, Duke could still have Joey Baker and is bringing in a wing in AJ Griffin as well as being all in on another wing/forward in Patrick Baldwin, Jr. PBJ is good friends with Christie and I could see Christie, Griffin, and Baldwin being a great combo on the floor together. I'm not sure Keels fits into that group unless he is fine being a guy that shares time with Christie or if Duke feels fine with Baldwin at the tallest guy on the court. My guess is that Christie and Baldwin commit this summer or early fall and Keels looks elsewhere. But who knows?
