SEATTLE — Chip Kelly wouldn’t even refer to his next opponent by name.

Fourth-ranked Southern California was just “them” according to Oregon’s coach in the moments after the 10th-ranked Ducks impressive 43-19 win over Washington on Saturday.

Kelly won’t bring up Saturday night’s showdown at Autzen Stadium until this morning. That’s fine, everyone else looking ahead to the showdown of Top 10 teams will do it for him.

“We’ll get on SC,” Oregon cornerback Anthony Gildon said. “We’ll take 24 hours and then we’ll get on SC.”

Now having won six straight after Saturday’s complete dismantling of the improved Huskies, the Ducks (6-1, 4-0 Pac-10) continue to make their season-opening meltdown at Boise State a distant memory.

In less than two months, Oregon has made a season that could have become defined by an embarrassing loss and LeGarrette Blount’s infamous punch, into one where the focus is on a stifling defense, opportunistic special teams and an always potent offense.

After Saturday’s win, Kelly almost sounded like the loss in Boise might have become the best thing for his team.

“We were young and inexperienced, and learned how to play then,” Kelly said. “So it is the same team, but they’ve learned when you’ve made a mistake ... you have to learn from those mistakes and correct them and move on.”

Now they’ll fall under the nation’s microscope again this week with the Trojans coming to Eugene with control of the Pac-10 race at stake. But this time the attention will be on how Oregon has improved on the field and its return to the Top 10 of the regular season AP Top 25 for the first time since getting to No. 2 in November 2007.

“We don’t care about rankings. We don’t care about polls, nothing,” Kelly said. “Everybody is going crazy about the first week of the BCS rankings. It means nothing. ... and the teams that talk about it, what happens is they lose a game. The only way you get a chance to talk about it is get to the end of the year and then did you do what you were supposed to do.”

What Kelly did care about on Saturday was the re-emergence of an offense that slogged through its victory at UCLA two weeks ago when sparkplug quarterback Jeremiah Masoli was out with a knee injury.

After a scoreless first quarter against the Huskies, Oregon got the spark it needed with a second-quarter blocked punt for a touchdown. Then came 21⁄2 quarters of offensive domination with five touchdowns in six possessions.

In less than 27 minutes of game time, the Ducks rolled up 338 yards of offense in just 40 plays and outscored Washington 35-9 during the stretch.

Masoli, who said his speed was only at “70 to 75 percent,” was the key. Washington’s defense was lost trying to follow all of Masoli’s ball fakes and when he did keep it himself, the gaps opened by his offensive line were massive.

“We thought going into the game he might be injured, but he was fine. He was fine,” Washington defensive coordinator Nick Holt said. “A good nifty little player.”

USC 42, Oregon State 36: Allen Bradford rushed for a career-high 147 yards and two touchdowns, and Southern California avenged its only loss of last season.

Damian Williams returned a fourth-quarter punt 63 yards for a touchdown for the Trojans (6-1, 3-1 Pac-10), whose 27-21 loss to the Beavers last September prevented them from playing for the national title.

Sean Canfield passed for 329 yards and three touchdowns for the Beavers, who shredded USC’s vaunted defense for 482 total yards in a back-and-forth offensive game. Jacquizz Rodgers rushed for 113 yards and a score, and also caught a TD pass on an injured ankle for the Beavers (4-3, 2-2).

James Rodgers had a 7-yard TD catch less than two minutes after Williams’ punt return put the Trojans up 42-23 and Jacquizz Rodgers’ 1-yard TD plunge with 5:41 to play cut USC’s lead to 42-36. But the Trojans converted two third downs while running out the clock, with Bradford picking up one last with a stiff-arm in the final minute.

The Trojans still haven’t lost consecutive games to the same opponent since 2002, in the second year of coach Pete Carroll’s tenure.

Arizona 27, UCLA 13: Nick Foles threw two touchdown passes to Juron Criner, and Arizona (5-2, 3-1) overcame five turnovers to defeat UCLA 27-13 on Saturday and keep pace in the Pac-10 race.

Foles had a hand in all five of Arizona’s turnovers. The Pac-10’s leading passer threw three interceptions, had a fumble returned for a touchdown and botched a handoff that led to a fumble.

UCLA’s defense did everything it could to keep the Bruins (3-4, 0-4) afloat. All 13 UCLA points resulted from turnovers.

Stanford 33, Arizona State 14: Andrew Luck threw for 236 yards, Toby Gerhart ran for 125 yards and a touchdown and Stanford greatly boosted its bowl hopes with a 33-14 victory over Arizona State on Saturday night.

The Cardinal (5-3, 4-2 Pac-10) used a balanced attack to match their 2008 win total and end a three-game losing streak in the series in which they had been outscored 120-23 by the Sun Devils (4-3, 2-2), including 41-3 here in 2007.

Stanford is trying to earn the school’s first bowl berth since 2001 in coach Jim Harbaugh’s third season.

California 49, Washington State 17: Kevin Riley threw for touchdowns on his only three passes of the first quarter, Jahvid Best scored three touchdowns and California  beat Washington State 49-17 Saturday.

Riley connected with Best, Marvin Jones and Shane Vereen as the Golden Bears (5-2, 2-2 Pac-10) scored 28 points on its first 11 offensive plays to break out to the early lead and cruise to the win.

The Cougars (1-6, 0-5) gained 299 yards in the first half and finished with a season-high 440.

UC Davis 34, Portland State 31: Greg Denham and Austin Heyworth combined for 341 yards passing and three touchdowns to rally UC Davis to a 34-31 non-conference victory over Portland State on Saturday.

UC Davis (4-3) trailed most of the game while Denham, the starting quarterback, was at the helm. But Denham (20 of 35, 259 yards, TD) was forced from the game with an injury midway through the third period, with Portland State ahead 28-17.

The Aggies then caught fire behind Heyworth, the backup, who wound up 6 of 7 for 82 yards and two touchdowns. Sean Kelley’s 30-yard field goal with 4:40 to play broke a 31-31 tie.

Marshfield graduate Bobby McClintock had a touchdown reception and touchdown run for the Vikings.
