Playing third-fiddle to fellow Duke seniors J.J. Redick and Shelden Williams doesn't bother Sean Dockery at all. He gets plenty of attention and respect where it matters most — in his own locker room.

"If people overlook me, oh, well," Dockery said. "My team and my coach, that's my family, and they know what I'm doing. That's a great feeling."

Helping No. 1 Duke stay unbeaten feels pretty good, too.

Dockery made a go-ahead 3-pointer and set up another an instant later by Lee Melchionni to help the Blue Devils beat No. 14 North Carolina State 81-68 Wednesday night in Durham, N.C.

Redick had 28 points and Williams added 21, but it was Dockery's plays down the stretch that helped Duke reach 17-0 (5-0 Atlantic Coast Conference) for only the second time. The other was during a run to the NCAA title in 1992.

"That's the best team we've played," Blue Devils coach Mike Krzyzewski said. "They know what they're doing and they do it well. It's a big win for us."

The Wolfpack (14-3, 3-2) were never too far away in a game that featured 16 lead changes and nine ties, the last at 65 following a free throw from N.C. State's Gavin Grant. On the other end, Dockery swished a 3 as Tony Bethel slammed into him.

When his free throw clanged off the rim, Dockery chased down the rebound and found Melchionni alone at the top of the key. His jumper also found the mark, and suddenly, the Blue Devils had a six-point lead. They never were challenged again.

"Plays like that, we practice that a lot," Dockery said. "Coach always talks about plays that take the life out of the other team. And that play right there, that's what it did."

They trailed at halftime for only the second time this season — the other came against Virginia Tech on Dec. 4. That's when Dockery made a 40-foot heave at the buzzer to give Duke the improbable victory. He made sure this one had little drama in the final seconds.

And his effort came on a gimpy foot that nearly caused him to sit out the game.

"I didn't think Sean was going to be able to play," Krzyzewski said. "We were a little bit worried it might be real serious, but it wasn't. He played hurt, yet you wouldn't know it. I'm proud of him."

Duke closed this game with a 16-3 run. Earlier this month, the Wolfpack saw North Carolina score the final 13 points to win 82-69.

"I can't compare games," N.C. State coach Herb Sendek said. "I thought our team played great basketball. Our guys have nothing to be ashamed of. Our guys competed really hard and played really well. I want them to feel good about themselves."

Cedric Simmons had an incredible game for N.C. State, finishing with a career-high 28 points, nine rebounds, seven blocks and three steals. Grant scored 13 points, his first game in double figures in more than a month.

But he and Simmons couldn't overcome uncharacteristically poor games from Engin Atsur and Ilian Evtimov. They each scored only two points, about nine below their averages.

"We've got to learn how to finish," Simmons said. "It was kind of the same thing that happened at the Carolina game. But I got some confidence and I learned that I can play with the best."

NO. 2 FLORIDA 113, SAVANNAH ST. 62: At Gainesville, Fla., Joakim Noah had 21 points on 10-for-10 shooting and reserve Walter Hodge added 18 points as Florida remained unbeaten. The Gators (17-0) extended the best start and longest winning streak in school history, and finished undefeated in non-conference play for the first time in coach Billy Donovan's 10 seasons.

NO. 4 MEMPHIS 88, TENNESSEE 79: At Memphis, Tenn., Shawne Williams had 21 points and 14 rebounds, while Rodney Carney added 22 points for Memphis. Darius Washington added 17 points and five assists, while Chris Douglas-Roberts finished with 11 points for Tigers (16-2), who won their fifth straight. Wiliams had four blocks.

NO. 9 PITTSBURGH 76, RUTGERS 68: At Piscataway, N.J., Aaron Gray scored nine of his 20 points in the final three minutes to help Pittsburgh remain undefeated. Levon Kendall had 14 points for the Panthers (15-0, 4-0 Big East). Quincy Douby, the Big East's leading scorer at 23.3 points per game, had 27 for Rutgers (12-5, 2-2), which scored only five points in the first 17 minutes of the second half as Pitt slowly pulled away.

NO. 19 OHIO ST. 77, NO. 15 WISCONSIN 67: At Columbus, Ohio, Terence Dials scored 15 points and Ron Lewis, Jamar Butler and Matt Sylvester each added 14 for Ohio State as the Buckeyes snapped Wisconsin's seven-game winning streak and handed the Badgers their first Big Ten loss. The Buckeyes (13-2, 3-2) scored eight straight points to take a 52-43 lead in the second half.

NO. 23 IOWA 76, MINNESOTA 72, (3OT) : At Iowa City, Iowa, Erek Hansen scored a career-high 20 points and Iowa relied on clutch free-throw shooting to win the first triple-overtime game played in Carver Hawkeye Arena. Iowa (14-4, 3-1 Big Ten) made nine straight free throws during a stretch of the second and third overtimes, while the Gophers (9-6, 0-4) went 5-of-12 from the line in the extra periods, including missing four straight when they had a chance to seal the victory in the final minute of the second overtime.
