I pulled for Texas. Always for the BIG 12 team when playing outside the conference (even when it is KU!)...
The only time I ever pull for USC, UCLA, OHIO STATE, MICHIGAN, MIAMI, OR THE FLORIDA TEAMS are when they are playing Notre Dame...I get very tired of the attention these teams have gotten over the years.
I am very pleased to see the many upsets we have seen this year. I hope parity doesn't get as ugly as it is in the NFL (see St. Louis Rams), but it is refreshing to see more teams able to compete.
You are right about rooting for MU and KU...they can bring the most attention to the conference this year!
