Gonzaga received the top overall seed for the NCAA tournament, with Arizona, Kansas and defending champion Baylor joining the Zags as No. 1s.
The March Madness bracket came out Sunday for a tournament that begins with early-round games Tuesday and concludes with the Final Four in New Orleans on April 2. The championship game is April 4.
This marks the return to the first "normal" tournament since 2019, with teams scattering to jam-packed arenas in eight cities for the first weekend, then to four different destinations for Sweet 16 before the fun ends in the Big Easy for the semifinals and title game.
"This was a really special year because we all realized what we missed," said Villanova coach Jay Wright, whose team, a No. 2 seed, won the Big East title in front of a packed house at Madison Square Garden.
The tournament was scratched in 2020 because of the then-erupting COVID-19 pandemic. Last year, all the teams played in front of limited crowds in a makeshift bubble in and around Indianapolis. One thing that remains the same: Last year's finalists, Gonzaga and Baylor, are top seeds, with the Zags the favorite to win it all.
Coach Mike Krzyzewski's last tournament has Duke playing in the West, meaning he might have to get past Gonzaga in the regional final to make his 13th Final Four.
Dayton, Oklahoma, SMU and Texas A&M were the "first four out," meaning there's still a glimmer of hope for them if a team must make a late withdrawal because of COVID-19.
Dayton would have been in were it not for an upset in its Atlantic 10 conference tournament. Richmond slipped past Davidson for the title, and while Davidson made the field, Dayton did not.
"Our committee really liked Dayton,'' said selection committee chair Tom Burnett. "They were deserving of consideration but unfortunately, the ended up on the `first four out' list."
Teams that just slipped in included No. 12 seeds Wyoming and Indiana, who will square off in the First Four. Rutgers and Notre Dame were the other last two teams in, while Michigan was seeded 11th, as well.
The Fighting Irish, Hoosiers and Wolverines are among the nation-leading nine teams to make it from the Big Ten. That's the same number as last season, but the conference only moved one team to the second weekend. The Big East, Big 12 and Southeastern Conference placed six teams each.
