The second round of the NCAA tournament gets underway Saturday, and there are only nine perfect brackets left in the ESPN Tournament Challenge.
There were 17.2 million brackets entered in the ESPN Tournament Challenge for the 2019 NCAA tournament.
After one round, only nine are still perfect.
The tournament's first 32 games captivated audiences as always, and like in most years, they also poked holes in many people's predictions on how the Big Dance would play out.
Of all the upsets that took place, No. 11 Ohio State over No. 6 Iowa State in the Midwest Region and No. 12 Liberty over No. 5 Mississippi State in the East Region had the most lasting effects on brackets.
Nearly 30% of ESPN brackets had Iowa State in the Sweet 16 and almost a quarter of them had Mississippi State making it that far.
For CBS though, not as many people were able to predict three 12 seeds advancing along with No. 13 UC Irvine and the No. 11 Buckeyes. There is only one unblemished bracket in their competition following Friday's action.
