It seems like ISU did a great job of stopping heavy running teams, which the defense was not designed to stop and the passing teams it was, ate us alive. TCU, Baylor and a few others moved up and down the field on the defense, while power running teams like Iowa struggled. The killer against the defense was if you had a mobile QB that could run and throw, thinking Kansas a few games and others, but those types of QB kill everyone.
In games we gave up 20+ points in, opponents consistently had 100+ rush yards and often more than that. That's not acceptable when your own team plays ball control, limit possessions football like we did.
KSU: 21 points, 110 rushing
COLO: 24 points, 140 rushing
ASU: 24 points, 290 rushing
(We let Jeff Sims run for 200+ yards...)
CIN: 38 points, 260 rushing
BYU: 41 points, 103 rushing (outlier here, since they threw for 300+ instead)
We were 12th in the conference in Rush D per attempt, giving up 4.4/carry on the season. That's not a great job at all, that is
way below average for CFB. We were right in the middle of the conference in pass yards/attempt, which I would guess was more related to just having fewer attempts put on us overall. We tended to let teams pass if they wanted to pass even at the height of our defense teams, opponents often couldn't score in the red zone instead. That was still mostly true last season from a passing perspective.
