The recruitments of two in state bigs; one in 1988 from ESL Lincoln, the other from Chicago Simeon in 1989, demonstrate what happened to Lou Henson.
In 1988, Collins and Henson went through ESL Lincoln HC Benny Lewis. ND and John Shumate quietly went through another third party (former grade school coach, summer league coach?) Lewis was as surprised as anyone when the kid picked ND. He had looked like an Illini lock until wavering days before fall signing.
In 1989, Collins and Henson went through Simeon HC Bob Hambric. They respected his wishes that his players wait until spring to announce. Bruce Pearl of Iowa hired a Simeon student to serve as his street agent. Pearl pushed the kid to commit early and secretly recorded conversations.
There were lots of twists and turns. Too many to go over right now. We all know about the conversation Pearl recorded and turned over to the NCAA. The were holes in Pearl's story and they were about to drop the whole thing. Then the kid from ESL was interviewed by Mike Slive.
It was not NCAA sanctions per se that hurt Henson's program, it was the changes in the recruiting landscape. The NCAA sanctions were a side effect.
