Hey, upsets happen every week. It befuddles me that the Nebraska of the last 20 years cannot ever make that happen. Usually we get our *** kicked when we're a big underdog.
But to answer the question-- I think our defense is good enough that we can be in any game this year if we don't turn the ball over, do not have any pre-snap and 15 yard penalties, win time of possession and have the special teams play lights out.
But alas, Scott Frost's teams are not known for any of that so I guess we'll just have to hope that OU plays poorly and we get some lucky bounces.
