Washington Cannot Keep Up, and Oregon Keeps Rivalry One-Sided SEATTLE - Marcus Mariota was finally contained Saturday. He was trapped, boxed in. It took two concrete walls, a narrow walkway in between and a few dozen reporters in his path, but finally Mariota was stopped. Mariota, Oregon's quarterback and the increasingly clear Heisman Trophy front-runner, spent much of the afternoon unobstructed. He dodged linebackers and fooled cornerbacks in the Ducks" 45-24 victory over Washington. He threw for 366 yards, ran for 88 yards and accounted for four touchdowns. One run took the shape of an S. Finishing a sixth straight game without a turnover, he has compiled 25 touchdowns on the season. Afterward, with microphones and notepads shoved inches from his face, bringing him finally to a halt, Mariota shrugged off questions about whether he impressed himself and whether he could appreciate this type of performance, the superhuman kind. He made it sound routine, and that was exactly how it looked for Mariota and the Ducks (6-0, 3-0 Pac-12). The coach Mariota flummoxed this week was Steve Sarkisian, who opened his news conference by saying his team had battled. "We just unfortunately had a hard time containing Marcus Mariota," Sarkisian said. We tried to catch him. We tried to spot him. We tried to blitz him. We tried to contain him. None of it worked. Not Saturday. And not this season against Oregon, which bolstered its status as a national championship contender against the Huskies (4-2, 1-2), as its chief rival for Pac-12 supremacy, Stanford, fell to Utah. Washington fans arrived dressed in black, and they packed the parking lots around Husky Stadium hours before kickoff. It was, naturally, an anti-duck crowd. Fans cooked ducks and ate ducks. The hung toy ducks with nooses around their necks. They quacked at those clad in Oregon Ducks T-shirts. As the morning wore on in typical overcast Seattle fashion, an upset seemed, if not likely, then not impossible. The Huskies play home games in a setting unlike any in college football, their stadium next to tranquil Lake Washington, the bobbing boats in stark contrast to crowd noise so loud it shakes the stands. Huskies hate Ducks more than they hate their in-state rivals and that works both ways. That has made the last decade of this one-sided rivalry more difficult for Washington to stomach. Oregon entered the game with nine straight wins in the series, by an average of more than 25 points. When the Ducks topped the Huskies again this season, a green sign hung in the front row of the stands. "Decade of dominance," it read. "For the fans, for the alumni, it is huge," Coach Mark Helfrich said. It's a big deal. By the same token, it's No. We had to get through the sixth game. The Ducks played without their best running back, De'Anthony Thomas, and they temporarily lost their best receiver, Josh Huff, to a leg injury. But Oregon did what Oregon does, turning a football game into a track meet: a blur of white jerseys, the numbers indistinguishable, the players interchangeable, bounding up and down the field. Oregon led by 21-7 at halftime, after its defense - and yes, Oregon can play defense - forced two turnovers and Byron Marshall ran for two touchdowns. ESPN's "College GameDay" had traveled to Washington's campus for the first time, for the Huskies, who won their first four games and nearly upset Stanford last week on the road. So it is in the resurgent Pac-12, now a power even among the major conferences: the Huskies faced a top-five team in Stanford one week and another top-five team in Oregon the next week, as part of the college football spotlight has shifted west. Huskies running back Bishop Sankey continued to make a national impression. He gained 174 yards on 28 carries and scored two touchdowns, both of which closed the deficit to one touchdown. The Seattle Times reported earlier this month that Sankey's grandfather, who had been blind for more than 30 years, had a cornea transplant and watched his grandson play for the first time last week against Stanford. He saw this game, too. But both times Sankey scored, Mariota answered. He always answered. He found Huff for a 65-yard touchdown, the pass dropping into the smallest of windows. He scrambled away from pressure. He barrel-rolled into the end zone. Scott Frost became Oregon's offensive coordinator this season, and he took over the play-calling duties from Chip Kelly, the Ducks" head coach who left for the N.F.L. Frost was asked, in the same crowded interview corridor, if he could rank this performance among Mariota's greatest. "Every time I call plays for him, I think that's the most impressive," Frost said. It's really easy to call plays when the ball is in Marcus's hands. Oregon hardly celebrated afterward. Players bumped fists as they carried sandwich boxes onto the team bus. Supporters patted one another on the back. The Ducks might have won 10 straight over their hated rival, but bigger games awaited. "We're not trying to make statements," Helfrich said, even as the Oregon band continued to play and Oregon fans continued to chant Mariota's name.
