While Zook is trying to keep Mitchell, the sources said, the role of recruiting coordinator isn't as all-encompassing as it sounds. It's important from an administrative standpoint, but Illinois has several staffers who are experienced at that. And while Mitchell has been a key Zook assistant, it might be time for a change, from both sides of that equation.
In addition, it wouldn't be surprising if Illinois' demoted defensive coordinators, Curt Mallory and Dan Disch, also left the staff. New coordinator Vic Koenning probably would like to make his own hires. Koenning also wants to handle the linebackers, which has been Disch's domain.
