Carson Beck threw for 278 yards, including a pair of touchdowns, and No. 1 Georgia opened another season of enormous expectations by stifling 14th-ranked Clemson 34-3 on Saturday.

Leading only 6-0 at halftime, Georgia finally got its offense rolling in the third quarter with a pair of 75-yard touchdown drives, capped by Colbie Young’s 7-yard reception and Nate Frazier’s 1-yard run. Beck tacked on a 40-yard TD pass to London Humphreys that sent the Clemson side of Mercedes-Benz Stadium heading for the exits.

Clemson was held to 188 yards and Nolan Hauser’s 26-yard field goal.

No. 4 Texas 52, Colorado St. 0 >> Quinn Ewers passed for 260 yards and three touchdowns and No. 4 Texas rolled past Colorado State 52-0 in the opener for both teams.

Ewers connected with Matthew Golden for a pair of touchdowns in the second quarter, and had another strike to Isaiah Bond as the Longhorns built a 31-0 lead by halftime.

Arch Manning came on for Ewers midway through the third quarter.

No. 5 Alabama 63, Western Kentucky 0 >> Jalen Milroe ran for two touchdowns and passed for three more, including scores of 84 and 55 yards to highly touted freshman Ryan Williams, and No. 5 Alabama breezed through Kalen DeBoer’s debut with a 63-0 victory over Western Kentucky.

Milroe played less than three quarters, completing 7 of 9 passes for 200 yards and running 10 times for 79.

DeBoer replaced Nick Saban, who led Alabama to six national titles in 17 seasons, after leading Washington to the national championship game. Saban and his family were at the game, watching his former team outgain Western Kentucky 600-145.

No. 6 Mississippi 76, Furman 0 >> Jaxson Dart threw five touchdown passes and ran for a score in leading eight consecutive first-half scoring drives, helping No. 6 Mississippi overpower Furman 76-0.

Dart opened the scoring with a 15-yard run and the Rebels raced to a 52-0 halftime lead in the opener for both teams.

Dart was 22 of 27 for 418 yards in the first half before yielding to Austin Simmons, who added a touchdown pass in the third quarter.

Ole Miss scored on first half series of 75, 90, 46, 20, 63, 81, 61 and 58 yards, highlighted by touchdown passes of 61 and 22 yards to Tre Harris. He had eight receptions for 179 yards.

No. 15 Tennessee 69, Chattanooga 3 >> Nico Iamaleava threw for 314 yards — a school record for one half — and three touchdowns in his first regular-season start to lead the 15th-ranked Volunteers to a 69-3 victory over Chattanooga.

Dylan Sampson rushed for 124 yards and three scores in the first half as the Volunteers had an easy opener against an in-state FCS foe.

Chattanooga, ranked eighth in the FCS preseason poll, didn’t cross into Tennessee territory until its first drive of the second half.

No. 17 Oklahoma St. 44, South Dakota St. 20 >> Alan Bowman threw three touchdown passes, Ollie Gordon II scored three times and No. 17 Oklahoma State ended two-time defending FCS national champion South Dakota State’s 29-game winning streak with a 44-20 victory.

Bowman, beginning his seventh year of eligibility at age 24, completed 25 of 34 passes for 265 yards in the opener for both teams. He threw scoring passes of 6 yards to Brennan Presley, 22 yards to Ollie Gordon II and 58 yards to Rashod Owens.

Gordon, a junior who won the Doak Walker Award as the nation’s top running back last season, carried 27 times for 104 yards and two scores. His second touchdown, on a short pass from Bowman, covered 22 yards for a 24-6 lead with 10:46 left in the third.

No. 18 Kansas St. 41, UT Martin 6 >> Avery Johnson threw two touchdown passes and Kansas State got contributions from all three phases of the game to lead the No. 18 Wildcats to a season-opening 41-6 win over UT Martin.

The Wildcats’ defense dominated early and often, allowing the Wildcats’ offense to find its footing. Kansas State limited the Skyhawks to 134 total yards (2.4 yards per play).

K-State also befuddled UT Martin’s passing attack by sacking Kinkead Dent three times. The Wildcats finished with four sacks, led by sophomore defensive end Tobi Osunsanmi’s 1 1/2.

No. 19 Miami 41, Florida 17 >> Cam Ward threw for 385 yards and three touchdowns — looking cool, calm and collected on a sweltering Saturday in the Swamp — and No. 19 Miami dominated Florida 41-17 to give coach Mario Cristobal a signature victory to start his third season at his alma mater.

The Hurricanes controlled both lines of scrimmage and never trailed in the renewal of a once-heated rivalry. The latest iteration was a one-sided beatdown, the kind that sent Florida fans scurrying for the exits in the third quarter and raised speculation about coach Billy Napier’s job security.

Napier fell to 11-15 in Gainesville, including 2-10 against ranked opponents. The Gators lost their sixth consecutive game overall and witnessed the end of their 33-game winning streak in home openers.

Now, Napier has the same number of losses at Florida Field in two-plus seasons (five) as Spurrier had in a dozen years.
