DURHAM, N.C. — Duke and Kentucky are viewed as the masters of the one-and-done era, winning championships with extraordinarily young rosters.

Both programs have a chance to do it again.

After several potential one-and-done phenoms were bounced from the NCAA Tournament in the opening weekend, the Blue Devils and Wildcats are the teams still playing that have rosters stacked with high-profile freshmen.

Duke, the No. 2 seed in the Midwest Region, starts four freshmen — led by Wooden Award finalist Marvin Bagley III — while Kentucky, the South’s No. 5 seed, features Kevin Knox as its centerpiece.

The Wildcats (26-10), arguably the biggest beneficiary of a run of upsets in the South, play ninth-seeded Kansas State on Thursday night in Atlanta. The following night, Duke (28-7) faces a rematch with 11th-seeded Syracuse in a Midwest semifinal in Omaha, Nebraska.

Hall of Fame Duke coach Mike Krzyzewski said his freshmen are “not afraid of the moment. It’s how much preparation do they have for the moment?

“We’re trying to condense about four years into eight months,” he said. “I don’t know how it’s going to turn out. You just kind of live it.”

Among the star freshmen who didn’t make it to the tournament’s second weekend were Arizona’s Deandre Ayton, Oklahoma’s Trae Young, Missouri’s Michael Porter Jr., Michigan State’s Jaren Jackson, Alabama’s Collin Sexton and Texas’ Mohamed Bamba. Young and Bamba have already declared for the NBA draft.

Both the Blue Devils and Wildcats have previously had predominantly young teams cut down the nets at past Final Fours. Kentucky won a national title in 2012 behind top-two draft picks Anthony Davis and Michael Kidd-Gilchrist, while Duke’s most recent national title came in 2015 behind three one-and-done freshmen — Jahlil Okafor, Justise Winslow and Tyus Jones.

This Duke team has looked capable of joining that squad, with four freshmen averaging double figures in their two NCAA Tournament games, led by Bagley’s 22.0 scoring average. Another of those freshmen, forward Wendell Carter Jr., believes the Blue Devils are “reaching our peak at the right time” and have “developed into a team that can crush another team, our opponent.

“I try not to look ahead about this being my last year or anything,” Carter said. “I’m just living in the moment.”

The Blue Devils have three players — Bagley, Carter and point guard Trevon Duval — in the top seven members of the 2017 recruiting class, according to 247Sports. The fourth freshman, Gary Trent Jr., was rated No. 17 by the service.

The highest-rated members of Kentucky’s class are Hamidou Diallo, Knox and Jarred Vanderbilt — who are ranked 10th-12th by 247Sports — as well as Nick Richards, who’s No. 18. (Point guard Shai Gilgeous-Alexander arrived as a relatively unheralded recruit.) No other top-20 ranked players are still playing in the NCAA Tournament.

Kentucky coach John Calipari said his group “needed to fail as a team” to figure out how to win. The Wildcats in January dropped out of the Top 25 for the first time since 2014.
