Not that long ago, then-Indiana head coach Kevin Wilson was looking for a guy who could revolutionize the Hoosiers’ struggling defense. He turned to Tom Allen in 2016, who agreed to become the team’s defensive coordinator.

Two years later, Wilson and Allen are on separate sidelines. Allen assumed head coaching duties after Wilson and Indiana parted ways after accusations of players mistreatment arose. Wilson is now the offensive coordinator with Ohio State.

Saturday, the two will go head-to-head as the Hoosiers take on the Buckeyes.

Wilson still has plenty of respect for his former defensive coordinator and believes Allen is doing a lot of good in Bloomington.

“He came in with his philosophy, has his charisma, his style, but he does a great job connecting with his players and he’s doing a heck of a job there,” Wilson said on Urban Meyer’s radio show on Thursday.

Allen has the Hoosiers at 4-1 entering Saturday’s matchup against Ohio State. They’re coming off a 24-17 road win over Rutgers. It was the first time the program won its B1G road opener in over a decade.

Ohio State is 5-0 and defeated Penn State 27-26 last Saturday.

Saturday won’t be the first time Allen and Wilson have gone head-to-head. Last year, in the season opener Wilson’s offense was too much, defeating Indiana 49-21.
