When teams at the Football Championship Subdivision level take on Football Bowl Subdivision teams, the result usually is a win for the big boys.

Of course, that doesn't always happen. North Dakota State has been a big exception, with six consecutive wins over FBS teams. The Bison don't play an FBS team this year, but there are several FCS candidates to pull off an upset. Here are some matchups to watch:

South Dakota State at Iowa State, Sept.‚ÄČ1: The Jackrabbits made it to the FCS semifinals last year. They lost standout tight end Dallas Goedert (second-round draft pick by the Eagles) and receiver Jake Wieneke (Vikings free-agent signee), but senior quarterback Taryn Christion (3,515 yards, 35 TD passes) is one of the best in FCS. Iowa State had a breakthrough 8-5 season that included wins over Oklahoma and TCU. This will be a tough hill to climb for the Jackrabbits, but it's not impossible.
