No. 3 Oklahoma made a case to reclaim that top ranking with a Red River Rivalry rout.
Then No. 1 LSU showed that it was, indeed, a worthy No. 1.
The Sooners smoked No. 11 Texas 55-17, ripping up their heated Big 12 rivals by Landry Jones and a defense that scored three touchdowns.
Texas came to the State Fair in Dallas undefeated but not yet tested by a ranked team. The Longhorns, with their inexperienced quarterback combination of David Ash and Case McCoy, couldn't up with Jones and his talented receivers.
All-American Ryan Broyles had 9 catches for 122 yards.
In Baton Rouge, La., LSU had little trouble with a Florida offense playing with a freshman quarterback who had never taken a snap in a college game.
Jacoby Brissett, playing because both John Brantley and Jeff Driskel were hurt, couldn't muster any offense against the Tigers.
It was the second straight week Florida was pounded by an SEC West heavweight. The Gators were trounced by Alabama 38-10 last week.
LSU took over as the No. 1 team in the country two weeks ago, jumping past preseason No. 1 Oklahoma.
No. 2 Alabama, which played Vanderbilt later Saturday, jumped the Sooners last week, leaving Oklahoma No. 3.
The Sooners might win back some of that support when the AP poll comes out Sunday.
No. 1 LSU 41, No. 17 Florida 11
BATON ROUGE, La. (AP) _ Spencer Ware rushed for 109 yards and two scores and each of LSU's quarterbacks passed for touchdowns.
Jarrett Lee gave the Tigers (6-0, 3-0 SEC) the lead for good on their second offensive play, hitting Rueben Randle deep over the middle for a 46-yard touchdown. Jordan Jefferson used a jump pass to Mitch Joseph for another score.
LSU's fast, fierce defense was too much for Florida (4-2, 2-2), which started freshman Jacoby Brissett at quarterback because of injuries to senior John Brantley and freshman Jeff Driskel.
Brissett was intercepted twice on deep throws, once each by safety Brandon Taylor and star cornerback Tyrann Mathieu.
No. 3 Oklahoma 55, No. 11 Texas 17
DALLAS (AP) _ Landry Jones threw for 367 yards a three touchdowns, Dominique Whaley ran 64 yards for another touchdown and the Oklahoma defense scored three more touchdowns.
Having slipped from first to second to third over successive weeks, Oklahoma (5-0, 2-0 Big 12) stomped its top rival almost as easily as it did lowly Ball State the previous week. The Sooners wound up with their most lopsided win in this series since 2003, when they won by a series-record 52 points.
The Longhorns (4-1, 1-1) couldn't get anything going on offense. Their only touchdowns came on a kickoff return late in the first half, and a pass in the final minutes when they were down by 45.
No. 8 Clemson 36, Boston College 14
CLEMSON, S.C. (AP) _ Tajh Boyd threw for a touchdown and ran for another before leaving with a hip injury.
The severity of Boyd's injury was unknown. He came in leading the Atlantic Coast Conference in total offense and has been the catalyst for the Tigers' first 6-0 start in 11 years.
Clemson (3-0 ACC) got five field goals from Chandler Catanzaro and 117 yards and a touchdown from tailback Andre Ellington to put away Boston College (1-5, 0-3).
The Eagles played without ACC preseason player of the year Montel Harris, who aggravated a knee injury in last week's loss to Wake Forest.
No. 6 Oklahoma State 70, Kansas 28
STILLWATER, Okla. (AP) _ Brandon Weeden threw for 288 yards and five touchdowns playing less than a half and Oklahoma State had its highest scoring game since 1970.
Jamie Blatnick recovered a fumble and leaped to tip an interception to himself for two of the Cowboys' four first-half takeaways, and Oklahoma State (5-0, 2-0 Big 12) scored touchdowns on all eight of its possessions before halftime against the nation's worst defense.
Kansas (2-3, 0-2) came in allowing a Bowl Subdivision-worst 44.3 points per game, and Oklahoma State had already surpassed that total with 4 minutes left in the second quarter on Weeden's second TD pass to All-American receiver Justin Blackmon.
No. 13 Georgia Tech 21, Maryland 16
ATLANTA (AP) _ Tevin Washington ran for 120 yards and two touchdowns and Georgia Tech's least impressive offensive showing of the season was enough.
Georgia Tech led 21-3 before holding off the Terrapins' fourth-quarter comeback.
Georgia Tech (6-0 overall, 3-0 Atlantic Coast Conference) matched its wins total from 2010, when it finished 6-7. The Yellow Jackets averaged almost 52 points in their first five wins and began the day ranked first in the nation in rushing and second in scoring.
Quarterback C.J. Brown, who replaced starter Danny O'Brien, had a 77-yard touchdown run early in the quarter for Maryland (2-3, 1-1). Davin Meggett, who had 86 yards rushing, scored from the 1 with 7:33 remaining to cut the lead to 21-16.
No. 16 West Virginia 43, Connecticut 16
MORGANTOWN, W.Va. (AP) _ Geno Smith threw for 450 yards and four touchdowns and West Virginia navigated through another slow start to win its Big East opener.
West Virginia (5-1, 1-0) struggled to a 10-9 halftime lead before erupting for 23 points in a 7:35 span of the third quarter to take control.
Connecticut (2-4, 0-1) was picked apart on defense for the second straight week and its offense was limited to 275 total yards.
UConn quarterback Johnny McEntee was chased around the field all game. His third-quarter fumble led to a touchdown that gave West Virginia the momentum for good.
No. 18 South Carolina 54, Kentucky 3
COLUMBIA, S.C. (AP) _ New starting quarterback Connor Shaw threw for 311 yards and four touchdowns for South Carolina.
Shaw, a sophomore who took over as starter this week from fifth-year senior Stephen Garcia, completed 26 of 39 passes and had no interceptions.
The Gamecocks (5-1, 3-1 Southeastern Conference) gained 639 yards in their biggest win in an SEC game since joining the league in 1992.
The Wildcats (2-4, 0-3) offense gained just 96 yards, and their quarterbacks threw four interceptions and just four completions.
No. 19 Illinois 41, Indiana 20
BLOOMINGTON, Ind. (AP) _ Nathan Scheelhaase and A.J. Jenkins hooked up on two long TD passes to lead the Illini.
Illinois (6-0, 2-0 Big Ten) is off to its best start since the 1951 team was 7-0.
Indiana (1-5, 0-2) lost its third in a row, still has not beaten a Football Bowl Subdivision team this season and has lost 13 consecutive games against Top 25 teams since a 31-28 victory over then No. 13 Iowa on Oct. 14, 2006.
Sparked by Shane Wynn's 99-yard kickoff return for a touchdown, the Hoosiers took a 10-0 lead early.
But Illinois came back with a 77-yard scoring pass to Jenkins, took the lead on Tavon Wilson's 66-yard fumble return for a TD and made it 27-13 at the half on Scheelhaase's 67-yard TD pass to Jenkins.
No. 20 Kansas State 24, Missouri 17
MANHATTAN, Kan. (AP) _ Collin Klein ran for three touchdowns and the Wildcats, who nearly blew a big second-half lead, improved to 5-0 for the first time since 2000.
Klein finished with 157 yards of total offense and John Hubert added 126 yards on the ground for the Wildcats, who had lost the last five matchups between the Big 12 rivals.
James Franklin was 19 of 35 for 214 yards passing for the Tigers (2-3), who came into the game averaging more than 500 yards of total offense. They only managed 326 against the Wildcats, most of that coming on a pair of long touchdown drives in the fourth quarter.
No. 21 Virginia Tech 38, Miami 35
BLACKSBURG, Va. (AP) _ Logan Thomas ran 19 yards for a touchdown with 56 seconds to play, capping a wild fourth quarter for Virginia Tech.
The Hokies (5-1, 1-1 Atlantic Coast Conference) rescued their chances of contending in the Coastal Division with the dramatic rally, and may have killed the hopes for Miami (2-3, 0-2).
And they did it less than 2 minutes after Lamar Miller scored on a 30-yard burst for the Hurricanes, giving them a 35-31 lead and forcing Thomas and the Hokies to respond.
Thomas did, with a big assist from David Wilson, driving the Hokies 77 yards in eight plays, finishing the drive with a draw play on which he went virtually untouched for the score.
No. 22 Arizona State 35, Utah 14
SALT LAKE CITY (AP) _ Brock Osweiler passed for 325 yards and three touchdowns and Arizona State forced five turnovers.
Jon Hays threw three interceptions in his first major-college start for the Utes (2-3, 0-3 Pac-12).
Osweiler had the third 300-yard game of his career to lead the Sun Devils (5-1, 3-0 Pac-12).
Utah had taken a 14-10 lead with 10:32 left in the third quarter on Hays' 2-yard TD pass to tight end Dallin Rogers.
Arizona State then scored 18 straight points in less than four minutes to take a 28-14 lead. The Sun Devils turned Utah's fifth turnover of the game into another seven points, with Osweiler's 12-yard TD pass to Mike Willie capping a 10-play drive set up by Reggie Dunn's fumble with 14:12 left to play.
Wake Forest 35, No. 23 Florida State 30
WINSTON-SALEM, N.C. (AP) _ Tanner Price threw three touchdown passes, Josh Harris rushed for 136 yards and Wake Forest beat Florida State.
Price was 21 of 35 for 233 yards with touchdowns covering 22 yards to Chris Givens, 2 yards to Tommy Bohanon and 8 yards to Terence Davis to give the Demon Deacons (4-1, 3-0) their best start to ACC play in school history.
Wake Forest _ a 10-point underdog _ trailed for only about five minutes of the first half, led the entire second half and rolled up 391 yards against one of the ACC's toughest defenses. Florida State (2-3, 0-2) entered giving up just 257 total yards per game.
E.J. Manuel, playing for the first time in three weeks, replaced Clint Trickett late in the first half and finished 19 of 35 for 286 yards with two touchdowns and two interceptions.
