Before the 2018 season, Ohio State's defense looked to be one of the best in the nation.
After giving up 31 points to opening-day opponent Oregon State, who would finish the season 2-10, some had their concerns but it was still not seen as a big deal. The defense progressively got worse, culminating in a 49-point collapse in Ross-Ade.
The coaching staff then stumbled upon Brendon White, who seemed to right the ship for the rest of the year.
By the end of the season, Ohio State's defense was not bad; it was average.
