DURHAM, North Carolina (Ticker) -- For a few moments, the basketball game between Duke and Atlantic Coast Conference foe Georgia Tech was inconsequential.
Duke coach Mike Krzyzewski collapsed but stayed on the sidelines for the remainder of the game.
During a timeout about 8 1/2 minutes into the contest against the Yellow Jackets, Krzyzewski, 57, was speaking to one of the referees when he fell to the floor. He remained on the court for about a minute, but got up and finished the timeout huddled with his team.
"I don't know if it's ever happened to you, but when you get up real quick, sometimes you get light-headed," Krzyzewski said. "Over my 30 years of coaching, it's happened a number of times. It hasn't happened this year at all because I haven't been getting up. I think it's the gym shoes. I was more friskier or whatever.
"Usually when you get up, you're feet are under you and when I got up this time, I was ahead ... I felt like a chump. Like someone hit me with an air punch and I'm out. I'm thinking 'What an idiot,' and I know I'm going to get it from my daughters and my wife ... I got to deal with that forever now. They have so much ammunition on me."
In the game, J.J. Redick hit five 3-pointers and scored 17 of his 26 points in the first half as No. 6 Duke took control early and beat No. 23 Georgia Tech, 82-65, for the 17th time in their last 18 meetings.
"I just wanted to come out in the first half with a lot of energy and set the tone, and I think I did that," Redick said. "I got some points off transition buckets when I got loose balls or steals. I was just trying to make plays all over the court."
A junior sharpshooter, Redick, who scored 33 points, including 11 in the final 2 1/2 minutes of Wednesday's 92-89 loss to Wake Forest, finished 6-of-15 from the arc.
Redick, who has scored 20-plus points in his last seven games, averaging 27 over that span, was 6-of-6 from the floor and added a season-high four steals. He is the NCAA all-time career leader in free throw percentage in Division I at 93.7 percent.
"He's good," Georgia Tech coach Paul Hewitt said. "His mentality is that he's not going to be stopped, that you're not going to discourage him from coming after you. I'm sure their coaching staff could tell you how much he's improved, but he looks like he's improved a whole lot to me."
After building a 44-35 advantage in the opening 20 minutes, the Blue Devils increased their lead to 67-48 with 10 consecutive points on 3-pointers by Sean Dockery and Redick and baskets by Shavlik Randolph and Shelden Williams with seven minutes to play. The Yellow Jackets didn't get any closer than 12 points the rest of the way.
Williams had 14 points, 12 rebounds and six blocks for his fifth straight double-double of the season for Duke (17-2, 7-2 ACC), which improved to 25-3 coming off a loss since the 1997-98 season. Daniel Ewing added 16, five rebounds and five assists and Randolph contributed seven points, nine rebounds and five blocks in 19 minutes.
"I thought Daniel (Ewing) led us very well today and Shelden (Williams) was so strong in the second half," Krzyzewski said. "J.J. (Redick) got us started with a good (effort). That was Shav's best game this year, not just since he's had mono, but this year."
The Duke defense played well, allowing Georgia Tech to shoot just 40 percent (26-of-65) while forcing 18 turnovers and 10 steals. The Blue Devils also blocked 13 shots.
Williams hit two free throws that snapped a 10-10 tie and Redick knocked down a shot from the arc that boosted the lead to 15-10 eight minutes in. The Blue Devils led the rest of the way.
Jarrett Jack kept Georgia Tech (14-6, 4-5) in the game with 11 points and five assists in the first half as Duke held a 44-35 advantage at the half.
Jack scored 18 points and Luke Schenscher added 11 and 10 rebounds for the Yellow Jackets, who have lost five of their last seven league games and dropped to 0-4 in league road games.
"Right now, we're not tough enough to do it (win on the road)," Hewitt said. "Point blank, no need in sugar coating it. We're just not tough enough right now to do it. I know we have it in us. I'm to blame as much as anybody, but to win on the road, you've got to show some toughness and I don't think we've done that. We haven't deserved to win a game yet."
