DURHAM, N.C. — Shaquille Powell did the power running for Duke. No. 20 Georgia Tech and its triple-option offense couldn't get anything going.
Powell ran for three touchdowns, and the Blue Devils dominated one of the nation's top rushing teams in a 34-20 victory Saturday.
DeVon Edwards returned a kickoff 100 yards for a score while Powell scored on runs of 1, 4 and 30 yards for Duke.
A week after some critical errors by the defense led to a loss to No. 17 Northwestern, the Blue Devils controlled Georgia Tech's quick-strike offense from the start.
"We came out with the mind-set that we weren't going to let that happen again," safety Jeremy Cash said.
The Blue Devils held the Yellow Jackets to 173 yards rushing, their fewest since they had 151 in a loss to Mississippi in the 2013 Music City Bowl, according to STATS.
"We're just not a very good offensive football team right now," Tech coach Paul Johnson said.
Thomas Sirk was 17-of-25 for 114 yards with an 11-yard touchdown pass to T.J. Rahming for Duke.
Justin Thomas pulled Tech to within 26-20 with his 12-yard TD run with 8:02 left, and the Yellow Jackets had the ball twice after that while trailing by one score.
But they were stuffed on four downs deep in Duke territory, a series before Thomas fumbled at his 39 after a hit from Cash with 2:12 left.
"I knew the game was on the line, we needed somebody to step up and make a play," Cash said. "And my teammates believed in me, and felt that I could do that, so I did just that, and was able to get the ball out."
Powell then took a fourth-and-1 handoff up the middle for the 30-yard touchdown run that iced Duke's second straight win over a ranked Georgia Tech team.
"We showed ourselves that we can step it up when we need to, and how we need to be to compete for championships and win the ACC," Powell said. "It showed the team that we can do something great."
NO. 8 LSU 34, SYRACUSE 24: Leonard Fournette posed for a photo with former Syracuse great Floyd Little after leading the visiting Tigers to another victory, a fitting end to another stellar day for the Heisman Trophy hopeful.
Fournette ran for a career-high 244 yards and two touchdowns, and Tre'Davious White returned a punt 69 yards for another score for LSU.
"He told me I did a great job," Fournette said of Little, a three-time All-American at Syracuse in the mid 1960s. My job is to make one man miss, and that's what I did."
Fournette had his second straight 200-yard game and fifth straight 100-yard game.
BC 17, NIU 14: Troy Flutie threw a touchdown in his first career start, and Jon Hilliman had a tiebreaking 21-yard scoring run to lift the host Eagles. Flutie, the nephew of 1984 Heisman Trophy winner and Boston College graduate Doug Flutie, completed 5 of 11 passes for 92 yards with one interception. It was his second career TD toss. His uncle had 67 from 1981-84. Freshman Jeff Smith, a former Clearwater Central Catholic standout, was 0-for-2 but ran for 56 yards on nine carries.
UNC 41, DELAWARE 14: Mitch Trubisky came off the bench and threw four second-half touchdowns for the host Tar Heels. Trubisky completed 17 of 20 passes for 312 yards, all career highs, and set a school record for single-game pass efficiency rating. He also added 39 rushing yards on six attempts. "Everyone else played really hard, so it made my job easy," Trubisky said.
INDIANA 41, WAKE 24: Nate Sudfeld threw for 205 yards and two touchdowns, and the visiting Hoosiers improved to 4-0 for the first time since 1990. Jordan Howard added 168 rushing yards and a touchdown for Indiana, which heads into next week's Big Ten showdown against No. 1 Ohio State riding a five-game winning streak. "The cool thing about where we're at right now is that we're really not clicking at the level we know we can," Sudfeld said.
LOUISVILLE 45, SAMFORD 3: Lamar Jackson threw one touchdown and ran for two to lead the host Cardinals. Jackson rushed for 184 yards, a school record for a quarterback. He scored on keepers of 14 and 13 yards in the first six minutes. His 73-yard run set up Brandon Radcliff's 2-yard touchdown run to make it 21-0.
N.C. STATE 63, S. ALABAMA 13: Matthew Dayes ran for three touchdowns, including a 77-yard sprint, and the visiting Wolfpack put up 42 first-half points. Dayes also scored on runs of 2 and 8 yards, and Shadrach Thornton added TD runs of 39 and 4 yards.
