So I'm looking at game by game stats for ASU and Skattebo this season. I am dismissing the UCF game because Skattebo didn't play due to an injury that week. Ironically, UCF wound up being the highest ranked run defense ASU faced all year. Had Skattebo played, they might not have been. Anyhoo...
KSU, BYU, and Utah were the best rush defenses ASU faced, ranking 30, 31, and 38 in rush yards allowed respectively.
The next tier of defenses they faced were Texas State, Texas Tech, Cincinnati, and Kansas. These schools ranked 72, 73, 75, and 81 respectively.
The last 5 schools had weak run defenses, to say the least. These are Arizona, Iowa State, Wyoming, Okie State, and Mississippi State, ranking 101, 105, 113, 128, and 131 respectively.
Looking at the best three schools, the average rush yds per game given up ranged from 125.6 to 134.0. Arizona State won all of these games, and rushed for more yards than BYU and Utah typically gave up. KSU gave up almost exactly what their season average was.
The middle tier of defenses gave up rush yards per game ranging from 157.1 to 160.6 and these four teams provided both of ASU's losses on the season. Texas State and Tech limited ASUs rush attack, but the same cannot be said for Kansas or Cincinnati.
The 5 weak run defenses allowed anywhere from 183.3 ypg rushing to a pathetic 225.2 ypg (way to go Miss St

)
As you might expect, Az State feasted on these teams.

Texas, by contrast, allows 104.5 on the ground, ranking 9th in the NCAA. Arizona State will be the highest ranked rushing attack we have faced. They rank #18, at 198.8 yards per game.
The best two rushing offenses we have faced this season are aggy and Arkansas. We held aggy 80 yards below their season average, and Arky 95 yards below theirs (both games were also on the road). In fact, there are only three teams who have exceeded their avg rush yards per game against us, those being Mississippi State, Florida, and Georgia the 2nd time.
Most of the time we have not only slowed down our opponents rushing attacks, but we have pretty much stonewalled them. Contrast this with ASU. Only three defenses managed to have a better than average day against them. It really will be a game of strength on strength. However, the magnitude of our strength on defense is consistently greater than ASUs magnitude of strength on offense. Does that make any sense?
Put another way, our defense typically hurts the opposing offense more than ASUs offense hurt the opposing defense, when comparing performance against the opponent's season averages.
