2021 SportsLine Upset Bracket Full of Surprises

SportsLine simulated every possible matchup 10,000 times and the team that won over half the simulations was selected to advance. In order to "simulate the madness," we also assumed that the Nos. 3-6 seeds with the lowest win percentage when compared to other teams of the same seed would be upset. With this approach, we nailed 15 of the 26 double-digit seed upsets in the first round the past four tournaments!
