I suppose it is possible, but I have a hard time thinking that any of the 3 mentioned are leaving to go elsewhere. Could they go to teams that have a better pedigree in college basketball? Yeah they probably can, but they aren't IMO going to get anymore NIL money or close to the adulation they are getting at Nebraska.
I would worry more about guys like Diop and Rice moving on to other schools. I think both of them could play a lot more next year. They both just need to get stronger and a little heavier. Diop might fill that Allick spot and be that hustle guy next year. I think there is lots of potential in those 2.
They do need a good big man out of the portal and a point guard is essential. I can't help thinking that Chucky Hepburn may come home and finish his senior year at Nebraska. Damon Benning has hinted at this a few times when you here him talk. He is probably talking out his arse but he usually knows what is going on around the metro area.
