I would be willing to bet the run percentage was higher in 2014 given our rush defense was far more susceptible.
The run percentage was higher but I don't think "far more susceptible" is accurate. This year, we're giving up 3.8 yards per attempt. Wisconsin torched us last year but in the rest of the games we allowed .... 3.8 yards per attempt.
And that's before you account for four teams that we've played this year missing their starting RB. The RBs we faced last year were FAR superior to the guys we've played this year.
You're right, but, I don't think there's much point arguing the semantics. Regardless of who was missing what or who had what, teams have chosen to run much less on this year than last. There's certainly a confluence of factors, but, one of them is also that Nebraska does a pretty darn good job defending the run this year. We faced several teams last year that didn't have overly talented backs, imho - but, our defense still gave up big chunk yardage on rush plays. And all games considered, we are giving up 111.9 YPG this year compared to 177.8 in 2014. I don't see this year's totals varying greatly.
I'm also leary to remove the Wisconsin game. I know why you did, and it's certainly another way of looking at the stats, but this has to go both ways. For example, consider the pass defense from last year. They held their own, allowing 209 YPG. But, when they faced probably their best passing attack against USC, they gave up 321. We didn't necessarily face an abundance of QB talent last year, but we consider that pass defense unit better compared to this year.
The point I'm making is that, obviously, stats can manipulated to support an argument.
Watching this team, I think we're far better at defending the run than 2014.
