The last two perfect brackets were busted on Friday when fifth-seeded Maryland defeated 12th-seeded South Dakota State. Twenty-four games into the 2016 NCAA tournament -- halfway through Friday -- there are no longer any perfect brackets remaining out of the approximately 13 million entered in ESPN's Tournament Challenge.
Last year, one bracket (out of 11.57 million) remained perfect after the round of 64, the first time there was a perfect first round in ESPN's Tournament Challenge since at least 2010.
