Heather Dinich details how Washington's recent play has established the Huskies as the premiere team in the Pac-12. (0:37)

EUGENE, Ore. -- From the East end of Autzen Stadium, a 9-year-old named Cooper watched in awe as his Washington Huskies took the field for warm-ups, as though there were nothing more exciting than lunges and toe raises.

For the past nine years, he hasn’t had much to celebrate when it came to the Washington and Oregon game.

He hasn’t had to live through all of Oregon’s 12-year, 4,723-day win streak over Washington. But shortly before his bedtime on Saturday night, he and his father got to watch that streak come to an end as the Huskies pummeled the Ducks 70-21.

So, if there were any lingering questions about whether or not Washington was the Pac-12’s best shot at the College Football Playoff, they should have been answered on Saturday. On back-to-back weekends, Washington dismantled the two teams that have shared the Pac-12/Pac-10 title since 2009.

With a 6-0 record, it marches into its well-timed bye week looking at a second-half schedule that seems more than manageable. Quarterback Jake Browning, who had eight total touchdowns (six passing and two rushing), is playing like a third-year starter while his offensive line is protecting him and opening holes and lanes up front.

But even with 682 total yards, the Huskies’ defense remains the staple of this team -- the interception on the opening drive was a not-so-pleasant indicator for Oregon’s freshman quarterback Justin Herbert of what was to come, as was the fact that the Huskies' defense kept the Ducks' offense from reaching double-digit yardage until more than halfway through the first quarter.

Oregon, with obvious flaws that teams have exploited lately, looked even more out of sorts thanks to the disciplined and surgical play of the Huskies.

And on a night when the Ducks honored their NCAA champion men’s and women’s indoor track teams and their Pac-12 champion softball team, it was even more evident how far Oregon -- two years removed from a Pac-12 title and a national title game appearance -- has fallen.

Oregon beat Washington 45-20 in 2014, and the Ducks were surging toward the College Football Playoff. Meanwhile, Washington coach Chris Petersen was working through an 8-6 season, his first as the team's head coach.

Now, the roles are completely reversed (though at this point the Ducks would be lucky to reach eight wins).

And at the beginning of the fourth quarter, Huskies fans had no problem reminding Oregon of that as they began waving at the fans heading for the exits. “Nah, nah, nah, nah,” they sang, “Hey, hey, hey, goodbye.” They echoed the chorus a few times, throwing their "W" signs up at the Oregon "O's."

And, just like on the field, Oregon didn’t have much of a retort.

The message is clear: Washington is here and not planning to go anywhere. So, goodbye to that 12-year losing streak and hello to an even more obvious national title contender.
