Well, its an 8-game conference schedule, so SEC teams get 4 non-conference games a year...and theyre clearly including bowl games in this count.
So after the OU game in 2015, thats Western Carolina, North Texas. and Northwestern. Then in 2016: Appalachian State, Virginia Tech, Ohio, Tennessee Tech, and Nebraska. And finally in 2017: Georgia Tech, Indiana St, UMass, and Southern Miss.
Time flies when youre winning games of no consequence....
