The muscular man with a shaved head appeared at Cardinals practices midway through the fall of 2017.
Sean Kugler had just resigned after nearly five years as head coach at Texas-El Paso and came to Arizona to visit friends, most notably Cardinals coach Bruce Arians and offensive line coach Harold Goodwin.
But it was a working vacation, too, and Kugler spent time coaching centers during practices and sitting in on meetings of the entire offensive line. Not long after Kugler arrived, he gave starting center A.Q. Shipley hand-written notes that critiqued his play and suggested ways he could improve.
