It would make sense to get him whether or not Jok is coming back. Is Iowa so well-stocked that we can't use another good athletic wing? No, we are not. Perimeter players right now are Jok, Bohannon, Williams, Moss, Ellingson and Baer (who is kind of a hybrid 3/4 man). Jok (and to some extent Baer) are the only proven commodities. Moss MIGHT be very good. Same with Williams. But we haven't seen enough of either to know for sure.
I'd rather get a true PG then add another wing when we have some depth there. His film looks pretty good but no other schools offered so I'd rather bank it for some top talent we can go all in on in 2017
