How did they manage to put together a unit that could consistently dominate the LOS and disrupt play for an elite team like OSU?

It’s not that unusual for mid-level teams to build top offensive lines. For whatever reason, seems like a lot of 3-star guys can be developed on that side of the ball and coached up into top units. Witness the extended periods of success Iowa, Wisky, Nebraska had doing that.

But the top d-line units in my recollection are almost always at the schools landing 30 5-star recruits per year—OSU, Georgia, Bama, LSU/Florida/FSU back in the day, etc.

So how did IU in 2 years get a unit that looked like one of the old SEC powers dominating an overmatched Big Ten team from the early BCS era? Is the defensive coordinator a wizard? Brilliant NIL transfer recruiting? Unbelievable luck? Or is OSU’s offensive line secretly trash and they just haven’t played anybody any good until now?
