Not a big fan of statistic like this in order.
The scope in this stat is so narrow, and such black and white stats are hard to determine variables behind, based on time of game and location on the field.
I.e. Ohio likely only faces runs at the start of the game until they blow the top off the scoreboard real early.
Easy for a DC to dial up his play calling duties when they are that predictable.
As other have pointed out, our competition was not the strongest when it came to running the ball. When we did face a team who runs the ball well, i.e., Louisville, they racked up over 200, but this very narrow scope excludes many of the called runs.
I'm a believer that our defense is actually very capable, just don't like the stat. S+P Ratings.
I'd ignore this.
