Gut-check game: at Wisconsin. Sure, the Michigan State game on the road is a big gut-check game, too, but the Spartans are in the other division. Nebraska could have a hard time getting to Indianapolis if it doesn't get past Wisconsin. And, of course, Big Red lost 48-17 the last time it went to Madison (and 70-31 the most recent time it played the Badgers away from home). Camp Randall can be an intimidating place for visitors to play, but Bo Pelini's team has to be ready to step up and stop the run.
Trap game: Fresno State. Coming a week before the more heavily-hyped showdown versus those Hurricanes, this one has all the makings of a trap. The Bulldogs have fielded a solid program for years, won 11 games last year and have been picked to win their division in the Mountain West. Plus, the game is on the road with a night kickoff before Fresno fans who will be foaming at the mouth. No overlooking allowed here.
