You see, dear moron, the Big 12 only has ten schools right now, and two of those ten schools happen to be TCU and WVU. If the Big 12 had been smart, they would have also added BYU and Louisville, gotten to 12, and fully solidified their conference.
Unfortunately, their intelligence (while greatly eclipsing yours) was not able to see that 'more on your side' is better than 'less on your side.' A situation that has plagued you the whole of your life, I'm sure.
