Ku has built a firewall between Bill Self and Adidas. Their ~$200 million Adidas contract does not directly link the coach and the company, as Louisville's did with coach Pitino.
So, for this to affect Self and Ku materially, there will have to be a "smoking gun" uncovered. If so, it may come from James Gatto, the lead Adidas official, who is a known "friend of Bill."
Whether the FBI chooses to go there or not, perhaps giving Gatto some relief for turning on Bill, no one knows. But without that direct evidence, I don't see this impacting Ku one twit, other than their foreign player (De Sousa) is probably cut loose, and they may lose some recruit(s) over the stench - Romeo Langford being front and center.
The NCAA will do what they did to North Carolina, exactly nothing. It's the FBI's criminal case that will bring down the sham program - if that case can be made.
