Mike Krzyzewski celebrated with his players on the makeshift Lucas Oil Stadium court after a game that looked lost until it wasn't.
Duke's fifth national championship came largely on the backs of two freshmen, just not the ones everyone expected.
First-year guards Tyus Jones and Grayson Allen scored 29 of Duke's 37 points in the second half while Jahlil Okafor and Justise Winslow battled foul trouble, sparking the Blue Devils to a come-from-behind 68-63 win over Wisconsin on Monday night.
Okafor, projected to be one of the top picks in this year's NBA Draft, picked up his first foul 1:49 into the first half and had four with more than nine minutes remaining in the game.
With Okafor and Winslow on the bench during long stretches, Jones and Allen took over, helping Duke climb out of a nine-point hole.
Jones hit the 3-pointer that gave the Blue Devils the lead for good with 4:08 left but Okafor, who went more than 27 minutes without scoring, finally got back on the board with two big baskets.
Jones then hit another big shot, a 3 to make it an eight-point lead with 1:24 to play. He ended with a game-high 23 points, two more than senior Wisconsin star Frank Kaminsky, and was named Most Outstanding Player of the Final Four.
Allen added 16 points for Duke (35-4), Winslow scored 11 and Okafor had 10.
Kaminsky led Wisconsin (36-4) with 21 points and 12 rebounds and Nigel Hayes scored 13. Sam Dekker missed nine of his 15 shots and scored 12 points and Bronson Koenig added 10 points, most of them early in the second half as the Badgers started taking control after the teams were tied 31-31 at the break.
