Ohio State’s off-season strategy just took a sharp turn, with finding a new defensive coordinator skyrocketing to the top of their to-do list. With Jim Knowles jumping ship to Penn State, the Buckeyes have some big shoes to fill. Whoever steps in will inherit a defense that led the FBS last season but will see a massive overhaul with eight starters needing replacement. However, they’ll have the advantage of having Caleb Downs, arguably the best safety in college football, securing the back end.
As Ohio State dives into their hunt for a new defensive general, let’s break down 11 contenders who could be the right fit for the Buckeyes’ high-profile role. We’ll start with a couple of familiar faces already on staff who could slip into the position seamlessly, then venture into five prospects from outside who carry the experience and ties that might be a perfect match for Ohio State. And because it’s always worth dreaming big, we’ll also consider four long shots that, despite their odds, shouldn’t be dismissed without a call from Ryan Day.
Jim Leonhard, Denver Broncos Defensive Pass Game Coordinator
Leonhard’s stint with Wisconsin from 2017-22 was a period of defensive brilliance. The Badgers were a constant force, securing a spot in the top 11 nationally for total defense in five out of six seasons. Fast forward to the NFL, and Leonhard has kept his reputation intact. In his role with the Denver Broncos, the defense stood firm, ranking third across the league for points allowed per game. Knowing Day often leans towards coordinators with NFL backgrounds, Leonhard’s blend of professional and collegiate success makes him a standout candidate. Convinced to rejoin college football, he could be the strategic mind Ohio State needs.
(It’s worth noting that Leonhard has reportedly chosen to continue his NFL journey, staying with the Broncos amidst a flood of interest for NFL defensive coordinator slots.)
Randy Bates, Pittsburgh Defensive Coordinator
With a strong Buckeye bloodline, Bates is no stranger to Ohio State. Stepping into the defensive coordinator role at Pittsburgh in 2018, Bates built robust defenses, notching three top-25 finishes in total defense across four years. Last year’s dip to 81st was a blip in an otherwise strong record. His Big Ten roots run deep from his 12 seasons coaching linebackers at Northwestern, and his earlier tenure at New Hampshire aligns perfectly with the Buckeye ethos, sharing connections with Day’s alma mater.
Jerod Mayo, Former New England Patriots Head Coach
Day’s recent affinity for hiring former NFL head coaches—seen with executives like Bill O’Brien—implies Mayo could bring valuable wisdom to bolster Ohio State’s defense. Mayo’s head-coaching reign with the Patriots may have been brief, ending after a solitary 4-13 season under the emerging shadow of Mike Vrabel. Nevertheless, his time as linebackers coach established him as a premier young assistant, doubling up as the unofficial co-defensive coordinator. His NFL journey positions him as a fresh, experienced voice who could innovate and inspire Ohio State’s defense.
As Day explores these enticing possibilities, the Buckeyes community awaits to see who will take the helm and strategize their defensive resurgence. Whoever lands the gig will carry the torch for a program hungry to remain at the peak of college football’s defensive ranks.
