OU hosts South Dakota and OSU hosts McNeese State, both Saturday, in mismatches against Division I-AA opponents. I wrote about the whys of such games for the Wednesday Oklahoman, which you can read here.
In my research, I found a bunch of interesting tidbits about games involving Power 5 Conference teams and I-AA teams:
* Five times has a I-AA team beaten a top-25 team from a major conference. North Dakota State beat No. 13 Iowa 23-21 in 2016, Eastern Washington beat No. 25 Oregon State 49-46 in 2013, James Madison beat No.
