OMAHA, Neb. — By the time the blue-and-yellow Werner ladder was in position under the basket, about 20 minutes before seven here, Malik Newman had already sank a pair of key free throws in the final minute of overtime. He had already delivered a series of offensive haymakers to the national championship favorite in the biggest game of his college career. He had already shuffled his feet to stay in front of Duke senior guard Grayson Allen and contest his would-be-game-winner to force the extra session. He had already slipped on a white celebratory baseball cap, headed over to press row and extended his hand.
