This year’s NCAA March Madness men’s basketball tournament has been nothing but extraordinary.

The 2018 tournament has been surprising, shocking, full of full buzzer-beating moments, and most notably, the year of the underdog.

Many firsts occurred over the first two rounds of the tourney.

For the first time in the men’s tournament, a No. 1 seed lost to a No. 16 seed in the round of 64. University of Maryland-Baltimore County (UMBC) routed heavily favored Virginia, 74-54. Many people had picked Virginia to win the whole thing, only to witness history unfold.

Also, for the first time ever, the top 4 seeds in a region of the bracket failed to reach the sweet 16. No. 4 Arizona, No. 3 Tennessee, and No. 2 Cincinnati all joined Virginia in the South region as teams underachieving and going home early.

Many Cinderellas remain in the tournament.

No. 7 Nevada overcame a 22-point deficit to Cincinnati to advance and meet fellow Cinderella No. 11 Loyola Chicago, which trailed 61-62 in both of their wins, only to hit game winners with only a second to go. They defeated No. 6 Miami and Tennessee to keep the dream alive.

West region No. 1 Xavier lost to No. 9 Florida State, which makes two No. 1’s eliminated in the first two rounds.

This year might be the most difficult year of all to pick a winning bracket.

The last team in the tournament, Syracuse, had to win a First Four game to enter the Round of 64 — and then ran off two straight wins, the latter against No. 3 Michigan State, another team that was supposedly destined to make a strong run to San Antonio.

Syracuse might be the most dangerous team in the tournament at the moment. The Orange are 7-1 as a double-digit seed in the tournament the past three years, starting with making it all the way to the Final Four in 2016 as a 10 seed.

Don’t count out Syracuse to win it all, but also don’t count out anyone else in the tournament. It’s just that kind of year.
