Another opinion (Sporting News article) that NU is NOT an intimidating place to play:
5. Nebraska: NU fans have the highest football IQ in the country. It's not even close. Love the way they applaud opponents when they leave the field. Now, as far as intimidation: I just don't feel it. A great atmosphere? Absolutely. But intimidating? Every now and then.
Of course everyone on this message board wouldn't hold a biased opinion <haha>. I was at the Notre Dame vs. NU game and even with all the Husker fans my ears were deaf with the Notre Dame fans. I've sat at many spots throughout Memorial stadium for raucous games that weren't nearly as loud.
