DURHAM, North Carolina (Ticker) -- After Mike Krzyzewski blew his cool, Duke blew a chance to extend the nation's longest home winning streak.
Freshman Luol Deng suffered through a miserable game and Krzyzewski threw a tantrum in the first half as the third-ranked Blue Devils had their home winning streak snapped at 41 games by No. 22 Georgia Tech, 76-68.
Krzyzewski let loose with an wild outburst, chewing out referee Karl Hess for failing to call a foul on Georgia Tech's Luke Schenscher. He was hit with a technical foul by Hess, then had to be restrained after screaming at Ray Natili, who did not eject Krzyzewski.
In the midst of Krzyzewski's histrionics, Georgia Tech (21-8, 8-7 ACC) embarked on a 17-3 tear that built a 31-19 advantage. The Yellow Jackets never trailed thereafter and took the lead for good with six straight points to snap a 56-56 tie, capped by an uncontested layup by Schenscher with 6:07 left.
Deng managed a season-low three points on 1-of-14 shooting for Duke (24-4, 12-3), whose last home loss was a 91-80 defeat to Maryland on Senior Night during the 2001-02 season.
"Georgia Tech played their butts off," Krzyzewski said. "They were deserving. We could never match that intensity for 40 minutes."
Despite the loss, Duke clinched the ACC regular-season crown with North Carolina State's loss to Maryland later in the night.
Georgia Tech ended a 15-game losing streak against Duke, posting its third straight road win. Jarrett Jack led the Yellow Jackets with 15 points and Schenscher added 14.
"We've come into this building the last three years and walked out of here feeling pretty low," Georgia Tech coach Paul Hewitt said. "We were beaten soundly by some outstanding Duke teams. This is another outstanding Duke team this year, and for our guys to come in here and play the way they did, it's a nice moment for those players."
One official that Krzyzewski did not try to intimidate was Ted Valentine, who is known for his quick trigger with ejections. Valentine called a charging foul on Deng with 4:22 left that helped stunt Duke's hopes of a comeback.
Deng was a big factor in Duke's 82-74 triumph at Georgia Tech on January 31 with 22 points and 10 boards. But the 6-9 forward, a leading candidate for national Freshman of the Year honors, turned in his worst performance of the season.
"We tried like crazy in the second half to win this basketball game, but this game had to be won over a 40-minute period," Krzyzewski said. "And the team that played the best won. I'm OK with that. There's no tears here."
The Yellow Jackets shot 51 percent (26-of-51) and held a 38-28 advantage in points in the paint. A major reason for their inside dominance was the work of the 7-1 Schenscher, who grabbed nine rebounds and got Blue Devils center Shelden Williams into foul trouble.
"We had them down and they forced a couple of turnovers at the end and started to make a run back at us," Hewitt said. "For our guys to maintain and hold on and steady themselves, that says a lot about how far a lot of these players have come."
Williams contributed 11 points and 10 rebounds, but four fouls limited him to 21 minutes. Without Williams, Duke was forced to the 3-point line and made only 8-of-29 attempts.
J.J. Redick attempted to pick up the slack with 20 of his 24 points in the second half. But Redick also struggled from the arc, hitting 4-of-12, and Duke shot only 34 percent (24-of-70) for the game.
