I actually think KU and their current roster construction is basically what Prohm wants ISU to be (and we were that last season). He wants to run that 4/1 four guard system, like the one with Morris, Mitrou-Long, Thomas, Burton, and Young.
1 = PG who runs the offense but can also score and defend 1-4
2-4 = rangy wings who can shoot, create their own shot, and switchable on defense
5 = traditional big man operating 1v1 with space on the block
He wants the 4/1. Even the PG is a notional player in that system, and what really matters is having enough interchangeable, "positionless" swingmen to play 1 through 4 who can switch to kill the opposing PnR game but not end up creating mismatches.

Haliburton
THT
Shayok
Jacobson
...was the same idea. Kansas is doing the same with all of their guards/wings and putting a dominant big man in Azubuike to abuse somebody 1v1 in the paint.
The archetypes of these guys are comparable, even if KU is obviously more talented. We had the personnel to run that last year with "1-4" positionless guys like Weiler-Babb, Haliburton, Shayok, and Horton-Tucker around, but we did not this year.
