This is a good start, but we need more. The question is how much do Nebraska opponents get flagged when they play Nebraska versus their averages against all other opponents? That will really tell the tale.
As I've said, the refs are rarely going to do something blatant to influence a game. It's much harder to detect small penalties that, when combined together, subtlety influence the outcome. Calling holding on Nebraska is an example. But the easiest way to do it is to refrain from penalizing the other team. That's how these guys are getting it down.
I'm willing to bet that our opponents have season-lows in penalties when they play us.
Did the research, its not as damning as you would think: Sorry for the formatting, don't know how to fix it :LOLtartar
Team: Penalties vs. NU - Yards Season Avg - Yards
Kansas St. 4-30 5.18 - 41.3
Texas 4-53 6.45 - 58.1
Oklahoma St. 8-84 6.09 - 63.6
Missouri 7-40 5.91 - 52.9
Iowa St. 3-40 6.45 - 51.3
Kansas 1-9 6.36 - 60.5
Texas A&M 2-10 8.7 - 68.8
As you can see, things start to get weird after Missouri. I'm not sure what to make of this - three games doesn't seem to be a big enough sample size to draw a conclusion. On the other hand, put into the context of when we became likely Big 12 North Champs (i.e. after we beat Missouri) things do look a little bit murkier.
Furthermore, raw stats don't take into account the sheer number of calls that are just plain weird (Gabbert forward-progress, Rex Burkhead's exorcist impersonation, the Eric Martin Suspension)or simple no-calls (i.e holding).
So anyways, for those who are curious that's how this breaks down.
