From 1988 until 1993 The Citadel went 6-1 over FCS teams: We beat Arkansas, Navy x2, Army x2, and South Carolina. Air Force beat us 10-7.

NDSU is the flavor of the year right now, but they have never embarrassed anyone like we embarrassed Arkansas (10-3) and USC (38-35), and it did not affect the FBS playing FCS landscape one bit.

I'd say suggesting a few wins over teams like Minnesota is the reason for the Big 10 dropping FCS games is leaning towards hubris.
