I'd guess 70-30 on Kofi staying. 80-20 on Ayo leaving. Based on nothing but wild speculation.
Kofi staying would be a huge relief. Ayo staying would be a huge surprise.
I'd say there's a chance Kofi comes back and Ayo goes, but it's also possible those two are flipped and Kofi goes but Ayo stays. And it wouldn't be shocking if they are both back, but then they could also both leave. Kofi may have his heart set on the NBA, but then he may really want to play professional basketball, which would be accomplished through the NBA but could also be accomplished through other leagues, and Ayo may feel the same way, or they may both value educations. They could value educations and ALSO value playing professionally, so don't rule that out either, whether or not they are drafted or not. I think Ayo might be a first rounder if teams feel that he has first-round talent and is one of the players they want to draft if and when they have a first round pick and it's their turn to choose someone. That could apply to Kofi, too. But if teams feel that either Kofi or Ayo wouldn't give them the best chance to have the best player available (or even the best fit for their team) at the spot at which they are drafting, then they may not choose either of them, in which case, they probably wouldn't be drafted at those spots. So it could imagine it going either way. I'd say it's like 80-40 that either one of them stays in the draft or returns to school.
I could also see it going the other way.
