New York ? Mike Krzyzewski was on one knee facing his seated team as he always is during a timeout. This time, however, was different.

Seventh-ranked Duke trailed Oklahoma by 10 points at halftime. The first play of the second half was an unforced turnover by the Blue Devils. Then came an Oklahoma basket on an offensive rebound.

Time out, Duke, just 33 seconds into the second half.

“It wasn’t about yelling or screaming. It was the time to say, ‘Look, either we’re men right now or we get run out of the gym. It’s time to be men,”‘ Krzyzewski said. “No strategy or anything like that. I thought our kids were men for the last 19 minutes. You can say whatever you want, but they have to do it, and they did it.”

Led by the big three of J.J. Redick, Daniel Ewing and Shelden Williams, the Blue Devils rallied for a 78-67 victory over the Sooners on Saturday night at Madison Square Garden. It is their fourth 8-0 start in the last five seasons.

Whatever the Hall of Fame coach said, it worked.

“We didn’t want to start the second half that way, not after the first half we played,” Ewing said. “He told us to wake up and get our heads out of our butts.”

Redick had 19 of his 26 points in the second half, turning a 1-for-7 effort from the field in the opening 20 minutes into 7-for-16 shooting for the game.

Ewing had 17 points, 12 in the second half.

Williams took over inside in the opening minutes of the second half, scoring seven points in a 10-2 run that brought the Blue Devils within 43-39 with 16:23 to play. Williams, a native of Forest Park, Okla., finished with 14 points and 13 rebounds.

Ewing and Redick missed only one of their first seven shots in the second half, and Duke made nine of its first 12. The suddenly effective offense led to much better defense as well, and Oklahoma (6-2) shot just 30 percent in the second half (9-for-30).

“I’m good when we’re good, and we weren’t very good in the first half,” Redick said. “We went to our motion offense in the second half, and that made the difference.”

Taj Gray had 18 points and 12 rebounds for the Sooners, whose only other loss was to No. 18 Washington in the semifinals of the Great Alaska Shootout. Kevin Bookout added 17 points, but was 2-for-10 from the field in the second half.

“It looked like we ran out of gas a little bit,” Oklahoma coach Kelvin Sampson said. “Our kids can play with that team, but we have to learn how to win it when you’ve got them. We have to find a way to make the play that will keep it right there.”

Duke had poor starts in its last two games — Toledo and Illinois-Chicago — but the Blue Devils took control in the first half of those home games.

Duke took its first lead against the Sooners since 8-7 when Redick hit a three with 11:12 to play that made it 53-52. That was part of an 11-2 run, during which he had the first nine points — a three-point play on a nice spin move and two threes. Ewing capped it with a basket that made it 58-52 with 9:35 left.

“We started hitting our shots and we got J.J. coming off some screens,” Ewing said. “We opened it up some more, and Shelden started playing offense the way he does in the second half.”

Redick was 8-for-9 from the free throw line, though the rest of the Blue Devils were just 12-for-21.

Duke’s Shavlik Randolph, who came in averaging 7.3 points and 5.7 rebounds, had no points and a rebound, fouling out in 14 minutes.

No. 4 Okla. State 79, UNLV 67

Las Vegas — Joey Graham had 20 points, and John Lucas added 17 as Oklahoma State remained undefeated.

UNLV made things interesting late, cutting the deficit to 71-63 with under two minutes to play. But Ivan McFarlin’s dunk with 1:38 left sparked the Cowboys’ 8-4 run that closed the game.

McFarlin also had 17 points for the Cowboys (8-0), who forced 21 turnovers and held UNLV to 40 percent shooting in their first game since beating Alabama-Birmingham 86-73 eight days earlier.

Romel Beck had a game-high 25 points for UNLV (3-4), and Jerel Blassingame added 19 and nine assists.

Colorado 89,

Colorado State 83

Boulder, Colo. — Marcus Hall scored 22 points, and Colorado hit 11 of 12 free throws in the final minute to hold off Colorado State. Richard Roby added 17 points, and Chris Copeland had 12 points and 13 rebounds for Colorado (4-2), which won its fifth straight over Colorado State. Matt Nelson had 26 points, and Matt Williams added 16 for the Rams, who had trouble overcoming a shaky first half. Colorado State (5-4) had just three turnovers and shot 58 percent in the second half, but it still wasn’t enough for its first win in Boulder since 1957.

Nebraska 71,

North Carolina A&T 49

Lincoln, Neb. — Joe McCray hit six three-pointers during Nebraska’s 35-10 second-half run to pull away. North Carolina A&T (1-9), which had trailed by as many as 13 in the first half, tied Nebraska (4-3) at 28 on Sean Booker’s three-pointer with 19:02 left in the game.

Baylor 75, Southern 62

Waco, Texas — Aaron Bruce scored 24 points, and Tommy Swanson added 19 to lead Baylor. The Bears (3-3) trailed early in the second half before three-pointers by Roscoe Biggers and Bruce fueled an 18-4 run that put them ahead 57-46 with 10:30 remaining. Chris Alexander led Southern (3-5) with 36 points.
