Prior to coming to Ann Arbor, Ed was the offensive line and running game coordinator for the Minnesota Golden Gophers. Before Minnesota he held a number of titles at Ohio State including OC,TE and offensive line coach.
Here is a write up from Ohio State's web site from a few years ago talking about Ed and what type of offensive line coach he is:
Behind Warinner's offensive line that has produced five NFL players in the last three seasons, including three rookie starters in 2014 -- Corey Linsley for Green Bay; Jack Mewhort with Indianapolis; and Andrew Norwell at Carolina -- the Buckeyes have ranked in the Top 10 nationally in rushing three years with a national ranking of 11th in the fourth.
