Instant analysis: Oregon 45, Washington 24

SEATTLE -- Here's a quick take on Oregon's 45-24 victory against Washington.

It was over when: Oregon QB Marcus Mariota hit Bralon Addison for a 3-yard touchdown with 7:37 left, turning a tight game into a three-touchdown margin at 45-24.

Game ball goes to: Mariota formally announced himself as a Heisman Trophy candidate with an epic performance. He completed 24 of 31 passes for 366 yards and three touchdowns. He also rushed 13 times for 88 yards and a touchdown.

Unsung hero of the game: With RB De'Anthony Thomas out with an ankle injury and Josh Huff shaken up in the first half, Addison, a sophomore, caught eight passes for 157 yards and two touchdowns. The Ducks have a lot of weapons. He's only the newest one.

What Oregon learned: Oregon learned that it can whip a quality foe on the road, even if it has to play its starters in the fourth quarter, which is highly unusual. But the confident Ducks probably already knew that. They just proved it to everyone else.

What Washington learned: The Huskies learned that they're not there yet. They challenged the Ducks, but it was still a 10th consecutive blowout loss in the series.

What it means: The Ducks officially announced themselves to the nation as national title contenders. It also probably means we don't have to spend much more time wondering about first-year Ducks coach Mark Helfrich.
