There are only 20 undefeated FBS teams as of October 4, 2015. Of those 20, only 10 are 5-0. Oklahoma State is one of the few that’s reached the 5-0 plateau. It’s the fourth time it has done so under Mike Gundy. The other three (2008, 2010 and 2011) were pretty memorable seasons.
Here are the 10 teams that are 5-0.
A pretty impressive (and weird) list (Iowa? Memphis?) And yet, despite defeating a previously-undefeated Kansas State team to get to 5-0 on Saturday evening, Oklahoma State actually moved down in the AP Poll.
