special teams coach. In that time, Johnson developed a reputation for being a premier blue chip recruiter, consistently landing top talent from the mid-Atlantic states. He was instrumental in the development of five first-team
All-Americans there:
Devon Still, first-round NFL draft choices
Tamba Hali,
Michael Haynes, and
Jimmy Kennedy, and former first-overall selection
Courtney Brown. Johnson was offered the

Tom Bradley announced that Johnson and linebackers coach
Ron Vanderlinden would serve as co-defensive coordinators. On January 7, 2012, Johnson was retained as a coach on the team's staff with the arrival of new head coach
Bill O'Brien. On January 1, 2014, Johnson was named interim head coach after O'Brien's departure to the NFL.
Ohio State Johnson left Penn State following the 2013 season after 18 years when he was hired by Ohio State to be an assistant head coach and defensive line coach. At Ohio State, Johnson is known for his ability to develop several highly-touted NFL prospects such as
Joey Bosa,
