March Madness is here. UConn, Purdue, Houston and North Carolina get top seeding in NCAA Tournament

Even before the brackets came out Sunday, March Madness was a muddled mess.

About the closest thing to a sure thing: UConn.

The defending champion Huskies earned the top seed in the NCAA Tournament, joined by Houston, Purdue and North Carolina as No. 1 seeds in a bracket that started going haywire even before the pairings were announced Sunday evening.

Of those top teams, only UConn heads into the tournament coming off a win. The others lost in their conference tournaments, yet those were hardly the only surprises over the final weekend of hoops before the sport’s main event hits center stage.

Unexpected titles placed teams like Oregon, North Carolina State and even Duquesne, none of whom were projected to make the tournament, into the field of 68 via the automatic bid that goes to conference champions. The teams they beat gobbled up a handful of the 34 at-large bids, thus shrinking the number of spots available to teams on the so-called bubble.

“It was one of the most difficult that I’ve been involved in,” Charles McClelland, the chairman of the selection committee, said of the process that had everyone up until 2:30 a.m. the night before. “And I talked to some of the staff that’s been in that room for the last 20 years, and they said this is probably the most difficult selection process that they’ve been a part of.”

It showed in a bracket that had its share of head-scratchers:

— Two of the last four teams in — Boise State and Colorado State — weren’t even considered on the bubble by most bracketologists.

“A little surprised to be honest,” Boise State coach Leon Rice said of his team’s No. 10 seed.

— Some of the teams left out — St. John’s and Oklahoma — were thought to be safely in as late as Saturday. St. John’s decided not to even play in the NIT.

“How is St. John’s so far off the cutline?” said UConn coach Dan Hurley, who was surprised only three Big East teams made it.

— Florida Atlantic and Texas A&M were considered bubble teams but ended up with 8 and 9 seeds, respectively.

All of this could be fodder for the growing conversation about expanding the bracket to 76, maybe 80 teams. Under that scenario, bubble teams like Pittsburgh, Seton Hall and even Indiana State would almost certainly be in.

The tournament starts Tuesday with two First Four games, including a matchup between Virginia and Colorado State. The 32 first-round games take place Thursday and Friday. The Final Four is set for April 6-8 in Glendale, Arizona.

UConn the favorite

UConn, which opens Friday against Stetson, is the favorite according to FanDuel Sportsbook and is trying to become the first repeat champion since Florida in 2006-07. The Huskies (31-3) are on a seven-game win streak and are tied with James Madison for most wins in the nation.

For all its excellence this season, UConn ended up in an East region with two of last year’s Final Four teams (San Diego State and Florida Atlantic) along with Iowa State, which is coming off a 69-41 win over Houston and was thought, for a minute, to be top-seed material.

“If we’re able to get to our identity … and then we play harder than you, we keep ourselves from being vulnerable that way,” Hurley said.

Conference bragging rights

Both the SEC and Big 12 placed eight teams in the field, while the Big Ten and Mountain West each had six.

Speaking of pride: Michigan State extended its nation-leading streak to 26 straight years in the tournament. The ninth-seeded Spartans will play Mississippi State on Thursday, the same day No. 5 seed Gonzaga plays No. 12 McNeese. In February, the Zags were considered a bubble team, but a stretch of nine wins in 10 games changed that, and coach Mark Few’s team made the field for the 25th consecutive year.

Small fry

The Ivy League is sending Yale, a 13 seed that needed a furious late comeback and a buzzer-beating basket against Brown to win the title and set up a game Friday against No. 4 Auburn. And Saint Peter’s back in the tournament, two years after making an unlikely run to the Elite Eight as a No. 15. This year, the Peacocks are 15 seeds again, opening against Tennessee in the Midwest.

Should Tennessee advance, coach Rick Barnes could face his old school, No. 7 Texas, which opens against the Virginia-Colorado State winner.

Meanwhile, Duquesne, the surprise winner of the Atlantic-10, is back in the tournament for the first time since 1977. A game against No. 6 BYU awaits.

Women’s tourney: South Carolina, Iowa, USC and Texas are the top seeds

(AP) — Undefeated South Carolina is the top overall seed in the women’s NCAA Tournament.

The Gamecocks are looking to become the 10th women’s basketball team to go undefeated for an entire season.

They had a chance last season before falling just short against Caitlin Clark and Iowa in the Final Four. The Hawkeyes received the other No. 1 seed in the Albany Regional.

The two teams wouldn’t potentially face off until the national championship game this time. Iowa is a one-seed for the first time since 1992.

USC and star freshman JuJu Watkins earned their first No. 1 seed since 1986 as the top choice in a Portland Regional.

Texas earned the fourth No. 1 seed, it’s first since 2004, and will play Drexel in the other Portland Regional opener.

South Carolina coach Dawn Staley’s squad has been challenged a few times this year, including needing a buzzer-beating 3-pointer from Kamilla Cardoso to win the semifinals of the SEC Tournament over Tennessee, but has always pulled through.

The Gamecocks, who are a No. 1 seed for the fourth consecutive year, will play the winner of Sacred Heart and Presbyterian in the first round of the tournament.

Joining the Gamecocks in the Albany Region are No. 2 seed Notre Dame, third-seeded Oregon State and fourth-seeded Indiana.

Clark, who became the NCAA’s all-time leading scorer this year, is trying to win her first title.

The Hawkeyes open up against the winner of Holy Cross and UT Martin. Joining the Hawkeyes in their region are No. 2 UCLA, defending champion and third-seeded LSU and fourth-seeded Kansas State.

The other top teams in USC’s bracket are Ohio State, UConn and Virginia Tech. The Huskies were the last team to go undefeated in a season, running through the 2015-16 season.

Texas could have to contend with No. 2 Stanford, No. 3 North Carolina State and fourth-seeded Gonzaga.
