Mike Krzyzewski has spent more than four decades at Duke telling his players what to do, with championship-level results.

With his Hall of Fame career in danger of coming to an end, Krzyzewski let his players dictate the game-closing defensive strategy of switching from an uncharacteristic zone defense into Duke's famous man-to-man.

The key defensive stops and two late baskets by Jeremy Roach moved Krzyzewski within one win of his record-setting 13th trip to the Final Four in his farewell season with a 78-73 win over Texas Tech on Thursday night.
