This is a disgrace...
I assume you mean that it is a disgrace that Oklahoma will play in the Big 12 championship instead of Texas. Could be, but why in the world did the Big 12 do something as stupid as having the BCS polling system determine who should play in its championship game? The Big 12 did something pretty stupid in my book.
You said “This is a disgrace”
I am confused, do you mean that Texas only beat OSU at Texas by 4 points or that OU only beat OSU at OSU by 20?
