6. Wisconsin Badgers at Nebraska Cornhuskers, Oct. 7
What's at stake: Nebraska improved by three wins in Mike Riley's second season, to 9-4, but it sure didn't feel like it after the Huskers dropped four of their final six games. Their final three losses came by a combined 103 points. It started to go wrong for Big Red after an overtime defeat at Wisconsin, which will enter the season as the Big Ten West division favorite and a fringe CFP contender. Although Nebraska has a revealing Week 2 trip to Oregon, it ultimately must compete for the division or serious questions will emerge about Riley's leadership. Nebraska entered the Big Ten pegged as a West heavyweight, but it has won the division once in six years. This game also carries stakes for Wisconsin, which skips both Ohio State and Penn State on the regular-season schedule.
