The Ames Tribune's Cyclone Slant podcast from today has some pretty good input from Travis Hines.
From what he gathers, ISU is pretty much out on Diallo so their recruiting strategy of swinging for the fences with top ten rated guys will probably end going into 2016 unless they make sense geographically or there is a relationship there.
He specifically mentioned the Malik Monk recruitment will die out this summer mostly because there is no geographic or relationship advantage for ISU so it will end.
Makes sense to me.
I hope when they back off Monk, though, that they give him a call and say why they're backing off but that ISU is of course still interested. Just to be polite, but also just in case he does actually want to come here...
You can make a pretty good team based on 30-100 guys.
