The Ohio State football program had to deal with multiple coaches from TTUN cheating against them. The NCAA punished multiple Michigan coaches for their roles in the scandal. Jim Harbaugh decided to run to the NFL instead of facing the punishments in college.
When Harbaugh left to become the head coach of the Chargers, he took defensive coordinator Jesse Minter with him. Minter was able to escape the show-cause penalty that the NCAA handed him, as well. It was pretty clear that neither Harbaugh nor Minter was ever going to coach in college football again.
TTUN was able to escape the harshest penalties after the Connor Stalions scandal was exposed. The NFL clearly doesn't care about the lack of integrity of these coaches. In fact, Minter has gone from disgraced college defensive coordinator to now getting a head coaching job in the NFL.
Former Michigan coach Jesse Minter gets head coaching job with the Baltimore Ravens
Minter was hired as the head coach of the Baltimore Ravens on Thursday. The Ravens fired John Harbaugh after 19 seasons, so they were in need of a new head coach. For some reason, they decided that Minter was deserving of the job as opposed to other candidates.
A former Ohio State defensive coordinator also got a head coaching job in the NFL, but he was not implicated in any wrongdoing at any point when he was with the Buckeyes. The Ohio State Buckeyes had to deal with the fallout from Michigan's cheating, but it seems the coaches involved got a slap on the wrist.
Anyone who has followed the NFL knows that organizations only care if they can get players and coaches who help them win. Anything that doesn't affect that is not something they are concerned with. That's why the Ravens don't seem to care about Minter's past in college football.
