Duke, Coach K on brink of Final Four after gutsy win vs Texas Tech

SAN FRANCISCO — With 4.8 seconds left and Texas Tech finally subdued, Mike Krzyzewski turned to the Duke fans behind his bench and threw a right fist in the air. It wasn’t exactly a haymaker swing, but who cares. At age 75, after staring career-ending elimination in the face for the second successive game, the Duke legend had lived to punch another day.

He’d coached a floor-slapping, defense-changing gem of a victory, delaying his retirement for at least two more days. The most captivating storyline of this NCAA tournament keeps going.
