Here is the conferece only SOS. https://www.teamrankings.com/college-football/ranking/in-conference-sos-by-other
As you can see the Big12 stacks up pretty poorly to most other conferences. I had been saying that for awhile, because it only made sense. Look at the list the toughest 19 schedules were all Big10 and SEC teams. Makes total sense as they dominated the top 15 in the rankings and they all had to play each other.
That says Texas played a much more difficult conference schedule than Kansas. Lol solid source!
