Tournament Challenge: 16 perfect brackets

After the wins by Tennessee and Creighton, there are now just 16 perfect brackets left out of 11 million plus in Tournament Challenge through 22 games of the Round of 64.

The win by 11-seed Tennessee knocked out a bunch of brackets by beating 6-seed UMass, although overall the Volunteers were taken in 43.3 percent of brackets, by far the most popular of the 11-seeds.

The remaining perfect brackets are split on the Oklahoma State-Gonzaga game, but none of those brackets has Eastern Kentucky beating Kansas.
