Here’s the 2015 NCAA Tournament field

Undefeated, top-ranked Kentucky was selected the No. 1 overall seed in the NCAA Tournament, while Wisconsin, Duke and Villanova received the other No. 1 seeds in the tournament.

The seedings and matchups for the 68-team field were announced Sunday afternoon, with the Final Four set for April 4 and 6 in Indianapolis.

The selection committee made several controversial decisions regarding its choices of the 36 at-large teams, with UCLA, Indiana, Mississippi, BYU, Texas and Boise State making the field, while Temple, Colorado State, Miami (Fla.), Old Dominion, Tulsa and Texas A&M were among those left out.

There was no debate about Kentucky, however.

At 34-0, the Wildcats swept through the Southeastern Conference with a roster so talented that Wisconsin coach Bo Ryan said the top five on the Wildcats’ bench could be the second-ranked team in the nation. Kentucky is No. 1 in the Midwest and plays its first two tournament games in Louisville, Ky.

“My concern right now is just making sure we’re in a great frame of mind, and this team right now is,” Kentucky coach John Calipari said. “We’ll take (Monday) completely off from basketball. We might watch some tape later (Monday) night, and that tape is going to be our Arkansas game. And it won’t even be with me. It’ll be with the staff. …

“You’ve got eight teams, and in my opinion, from that eight someone’s going to win the whole thing. After that, there’s some teams that have the chance to advance and do some stuff. But those eight teams? They’re really good.

The No. 2 seed in Midwest is Kansas, the Big 12 regular-season champ, and the Jayhawks would face Kentucky in the Elite Eight if both teams get that far. Notre Dame, the ACC tournament champ, is No. 3 in the Midwest, with Maryland at No. 4.

Wisconsin, which beat Michigan State in overtime in the Big Ten title game Sunday, is the No. 1 seed in the West, and selection committee chairman Scott Barnes said the Badgers would have been a No. 1 seed even if they had lost to the Spartans.

Wisconsin won a school-record 31 games in claiming the Big Ten championship in the regular season and the postseason tournament. Coach Bo Ryan guided the Badgers to the Final Four in Arlington, Texas, in 2014 behind All-America forward Frank Kaminsky. Now a senior, Kaminsky was the West Region Most Outstanding Player in 2014 before the Badgers lost to Kentucky in a national semifinal.

“It’s awesome. First No. 1 seed in program history,” Kaminsky said. “That’s an accomplishment in and of itself, but we have a lot of goals and aspirations in the NCAA Tournament. So we’re going to prepare for our first game and be ready we tip the ball up.”

Arizona, which received consideration for a No. 1 seed, according to Barnes, is the No. 2 seed in the West, and would face No. 3 seed Baylor if both teams reach the Sweet 16.

North Carolina is the No. 4 seed in that region.

Villanova received the top seed in the East, while Virginia, the ACC regular-season champ, is the second seed. The Cavaliers seemed to be in line for a No. 1 seed until they lost to North Carolina in the ACC tournament semifinals.

Even at 32-2, Villanova lacked the pristine resume of some of the competition for a top seed. The Big East regular-season and postseason champions went 5-1 against teams ranked in the RPI Top 25, with wins at Butler, at Providence and against VCU in Philadelphia. Arguably, Villanova’s victories don’t stack up in terms of pure cachet to several No. 2 seeds. The Wildcats mastered the tests they received, and the selection committee rewarded them.

Villanova’s opening opponent is Lafayette, coached by Fran O’ Hanlon, a Villanova graduate.

“In one way, this stinks,” Wildcats coach Jay Wright said according to the Morning Call of Allentown, Pa. “In another way, I’ m sure it’s going to make a great story and all that.

“The other thing is, (Lafayette is) really good.”

Oklahoma of the Big 12 got the No. 3 seed in the East, and Louisville is No. 4.

Duke, which won neither the ACC regular-season nor tournament title, earned the No. 1 seed in the South Region.

Virginia fell to the Duke in the only meeting of the season between the ACC teams, which helped provide separation in the final conversation for the top line. Duke also won at Wisconsin, at Louisville and had a 30-point victory over Notre Dame.

“We’ve won 29 games and have been one of the best teams in the country with four freshmen and eight guys,” coach Mike Krzyzewski said Friday after Duke’s loss to Notre Dame in the ACC semifinals. “I like my team. We’re ready to go to war in the NCAA Tournament, and we’ll take what the consequences are of our efforts.”

Gonzaga, the West Coast Conference regular-season and tournament champion, is the No. 2 seed in the South, with Iowa State No. 3 and Georgetown No. 4

The four at-large teams forced to play first-round games were BYU, Mississippi, Dayton and Boise State. That means they were the last four teams to get into the field.

The Flyers will play host to Boise State on Wednesday in one of the opening-round games.

“A couple years ago the committee decided if Dayton were to earn a spot we’d go ahead and make that decision,” NCAA tournament committee chairman Scott Barnes told CBS. “It was talked about quite a lot and it was revisited as late as last night. Certainly the decision to put them there falls within the context of our policies and procedures.”

Barnes said Temple would have been the next team to receive an at-large bid, and the Owls were doomed when Wyoming won the Mountain West Conference tournament title Saturday, removing one of the expected at-large spots.

Defending national champion Connecticut needed to beat SMU in the American Athletic Conference final Sunday to make the field, but the Huskies lost. Barnes did not say which at-large team would have been eliminated if UConn had earned an automatic berth.

UCLA, Indiana and Texas not only made the field but were not among the First Four teams that have to play first-round games Tuesday or Wednesday. That means they got into the tournament with room to spare.

The Bruins made the field in spite of losses against California and Oregon State, as well as a 32-point defeat to Utah in early-January.

“It was one of the tougher decisions the committee had to make,” Barnes told CBS. “Over the last month or so we felt they were gaining steam, they did have a good strength of schedule. They played better against tough competition, an example would have been the last game against Arizona. I think the eye test was a plus for putting them in the field.”

The Big 12 and Big Ten both got seven teams into the 68-team field, while the ACC and Big East had six apiece.
