This is the formula bonus given to defenses by my box score projection spreadsheet...
The formula gives bonus based on: Points allowed (weighted 1.5x) - rushing allowed (weight: 1), passing allowed (weight: 1), 1st downs allowed (weight 0.6). Compares the defense performance to their opponents averages - the higher the number the better. Only FBS opponents used in stats.

37% - Indiana
36- Texas
30 - Penn State
29 - Army

There are three defenses that stood out above the rest: Ohio State, Texas and Indiana.
The next tier includes Penn State, Army, Notre Dame and Tennessee.
Those 7 were the elite or near-elite defenses this season.
Lots of solid defenses, including Oklahoma in the next tier.
