According to the NCAA, the odds of a perfect bracket increase, in theory, to about 1 in 120 billion if you apply logic. That includes picking favorites. The closest known attempt was a bracket that remained perfect through the first 49 games in 2019. It was a remarkable bracket, but it was still light years away from perfection.

The Big Ten does not have a No. 1 seed, but they have eight teams in the top eight seed lines, led by Wisconsin.
