3-way tie, KState wins the first round of tiebreakers as they have no common opponents in which anyone lost. . . So the KState wildcats get the 1st seed.
Then 2-way tie, BYU gets the 2nd seed as BYU's win against KState is a victory against a common opponent (and the number 1 seed trumping a loss to Utah or Kansas).
So KState gets home uniforms, BYU will play in their away uniforms.
