I thought the Iowa-Nebraska series was developing into a rivalry of sorts. You have to give it more than 6-years to develop. When Nebraska joined the Big Ten I thought Nebraska would win around 65% of the games, and the fan bases would not look upon this as much of a rivalry.
With the series knotted at 3 apiece since Nebraska joined the conference, it was looking more like a rivalry game. Nebraska-Minnesota has been played a lot more times, so maybe they should have the game on Black Friday. I would enjoy seeing the back story on who pushed for which series to play the final game of the season.
