I don't believe what happened between Nebraska and Aguek will have too much of an impact on what Akol chooses to do. We've already seen Akol go out and make his own choices with him going to Creighton Prep over Omaha South for high school (South thought he was going there; they even had him on their bench at state as an eighth grader IIRC), and he has a different group around him offering advice/mentorship.
Right now, Nebraska is Akol's best offer by far. We'll see what the next two weekends bring, but Nebraska's in a good place right now, I'd say. I highly doubt he turns down Nebraska to go to UNO or UAB.
