I realize that Mack Brown is only 68, but, two octogenarian former SCAR college lamecock coaches come to mind to run their program: Richard Bell and Lou Holtz. Both were failures in lamecock land, but both know the state and the areas to recruit. Louser Holtz taught them to cheat, steal computers and use steroids. Perhaps they could be co-head coaches of the lamecock program? One could cheat and the other could complain about bad calls from the refs.
Seriously! Even the coots are not that dumb to get retreads. Older tires will be fine, considering you only need one, but not one who has been there before.
