Former LSU offensive linemen Blake Miller and Chris Truax were coaching OL's in college recently. Don't know if they still are or at what schools. I know they were mentioned as "Candidates" for the LSU OL job after Searles left and Stud was hired.
Dating myself a little here but: Ronny Estay - coached for many years in the CFL after a long playing career there Earl Leggett - was a long time asst. coach in the NFL after playing for the Raiders Johnny Nagel - I think he is still coaching somewhere
