Used to be a lot higher 
if you take away the last 3 seasons
That speaks volumes right there. 
Right on. Heres the difference
At the end of the 2003 season....
1. Kansas State... 49-15
Nebraska ........49-15
3. Texas .............47-17
4. Oklahoma.........41-23
5. Colorado..........39-25
Look at the North here at the end of 2003. 3 week years ruins the representation all together. Sporting News even claimed that a Big 12 North team has yet to win a National Title. I guess they forgot the 97 Huskers, but oh well.
