Big 12 has an interesting bracket setup for their tournament ....
A different group of seeded wrestlers get the byes in each weight class. For example, at 125, the 5, 6, 7, and 8 seeds got the 1st round byes, at 133 the byes were the 4, 6, 7, and 8 seed, at 141 the byes were the 1,2, 4, and 6 seed and so on.
