The word coming out of Nwora's visit to Northwestern is that he picked up an offer from the Wildcats and head coach Chris Collins. It's probably not terribly surprising that two former Duke assistants are interested in the same kid.
Nwora is listed at 6'8" tall on his 247 Sports page, but doesn't have a weight listed. Verbal Commits has him at 220 lb., which could make him an interesting stretch four option in the future. He has no rankings or ratings on 247, and VC has him as a two star prospect.
