Luke Fickell's been around the Ohio State block more than a few times in his life, especially in regards to defense.
Ohio State's co-defensive coordinator was born and raised in Columbus. He played for the Buckeyes under John Cooper from 1992-96, blossoming into one of the best defensive linemen in program history. After a brief stint in the NFL, Fickell returned as a grad assistant under Cooper in 1999, before taking a defensive line coaching position with the University of Akron in 2000-01. Then, Jim Tressel made Fickell his special teams coordinator in 2002. The man with 212 career tackles and now a pair of national championship rings hasn't left since.
