How about Ivan Rabb as a candidate to rise? Nbadraft.net already has him 5th, while Draftexpress and Chad Ford's big board are a little slower, having him at 10 and 11 respectively.
Or how about Ellenson? He's also really young (turning 19 in a few days) and is really versatile offensively.
I think one positive I get from reading some of these scouting reports is that some of the later lottery picks are at least being described as "athletic," which obviously helps at the NBA level. Rabb, Ellenson while not elite athletes by any means, seem athletic enough. Poetl is not a great athlete but he's very quick and agile and his position doesn't necessarily require great athleticism.
