Ohio State head coach Luke Fickell played with Mike Vrabel before Vrabel graduated from OSU and played 14 years in the NFL. Vrabel grew up the son of a football coach and always wanted to return to the Buckeyes to coach. The recent resignation/retirement of Jim Tressel has opened the door for Vrabel to retire from the NFL and take the linebacker coaching position vacated when Fickel was promoted to head coach.
