He may not (read: will likely not) stay in the position that long. But I think this is kind of a “final extension” to allow him the latitude to retire when he’s darn good and ready.
Whitt is your Kush. Keep him until he’s done. ASU was forever changed when Kush was pushed out and really hasn’t recovered. When he’s tired, let him retire with a plan and place so he can Barry Alvarez it as AD.
