It all changed in 2009. Since the turn of the century, the Ducks had essentially owned a struggling Stanford squad, winning seven straight by an average of 23 points. But in 2009, a rookie quarterback for the Cardinal changed the way people would view Stanford football.

Andrew Luck threw a pair of touchdowns and the Cardinal beat the No. 7 Ducks 51-42, igniting what has become one of the best intra-division rivalries over the past half-decade.

As the teams prepare to square off this week, here’s a look back at how things have played out over the last five games.

Nov. 7, 2009

Stanford Stadium

• Final score: Stanford 51, No. 7 Oregon 42

• The setup: The freshman Luck was already turning heads with wins against No. 24 Washington, UCLA and ASU. The Ducks, in their first year under Chip Kelly, were riding a seven-game win streak and were coming off a 47-20 thumping of No. 4 USC.

• Key play: Uh, every time Toby Gerhart touched the ball? He rushed for a school record 223 yards and three touchdowns on 38 carries.

• Remember this? It was offense galore as the teams combined for 49 first downs and 1,075 offensive yards.

• Quotable: "We got beat by a better team," Kelly said. "If you say we got caught looking behind or looking ahead, it takes away from Stanford. Stanford is a heck of a football team."

Oct. 2, 2010

Autzen Stadium

• Final score: No. 4 Oregon 52, No. 9 Stanford 31

• The setup: The revenge-minded Ducks blasted their way through the season (including Stanford), in what would be a run to the national title game. This was Oregon’s first game of the season against a ranked team, and the defense had posted two shutouts in its first four games. Stanford was coming off a road win at Notre Dame the week before. This would be the first time the schools met as ranked teams.

• Key play: Darron Thomas had just scored on a 6-yard rushing touchdown to tie the score at 31 early in the second half. But the momentum swung when Chris Owusu fumbled and Eddie Pleasant returned it 51 yards to the Stanford 3-yard line. LaMichael James scored on the next play, giving Oregon its first lead after trailing 21-3 early.

• Remember this? With the Cardinal trailing 45-31 late in the game, Cliff Harris intercepted Luck at the Oregon goal line for a touchback. Three plays later, LaMichael James scored on a 76-yard touchdown run.

• Quotable: "Wasn't our day today,” said Stanford coach Jim Harbaugh.

Nov. 12, 2011

Stanford Stadium

• Final score: No. 6 Oregon 53, No. 3 Stanford 30

• The setup: It had been building to this. The Cardinal had essentially trucked every team they played, save a dramatic 56-48 triple-overtime win at USC. Oregon had recovered nicely from its season-opening loss to LSU and had won eight in a row. Luck was the Heisman front-runner and new coach David Shaw had pushed all the right buttons so far. The Cardinal were riding a 17-game home winning streak.

• Key play: Trailing 29-16, the Cardinal were still in striking distance early in the second half. Stanford had just forced a three-and-out, but on their first play of the ensuing drive, Isaac Remington sacked Luck, forcing a fumble, and Brandon Hanna returned it to the Stanford 12. On fourth-and-2 at the Stanford 4, James delivered a 4-yard touchdown/knockout blow, putting the Ducks ahead 36-16.

• Remember this? The Cardinal couldn’t keep their feet. Part of it might have had something to do with the slippery James, who rushed for 146 yards and three touchdowns. But, per reports, the Cardinal hadn’t cut the grass for four days with the hopes it would slow Oregon. Instead, you had Stanford receivers and defenders who couldn’t keep their feet.

• Quotable: "We were slipping. They were slipping. I just ran fast," said James.

Nov. 17, 2012

Autzen Stadium

• Final score: No. 14 Stanford 17, No. 1 Oregon 14 (OT)

• The setup: The Ducks were rolling with new quarterback Marcus Mariota kid at the helm. They had won 10 straight to start the season and nothing, it appeared, would stand in their way of reaching the BCS title game -- let alone a Stanford team it had beaten twice with Luck. And who was this Kevin Hogan guy, making his first career road start in Eugene? The Cardinal had already dropped games at Washington and at Notre Dame. A third-straight win against Stanford, by another big number, was the probable outcome.

• Key play: Where do you start? The Jordan Williamson game-winner in overtime? The controversial Zach Ertz touchdown catch? The hustle play by Devon Carrington to bring down Mariota on his 77-yard scramble? Or the missed block by De'Anthony Thomas on Carrington that would have sprung Mariota? (Oregon would fail to score after going for it on fourth-and-2 at the Stanford 7). Take your pick.

• Remember this? Oregon was riding a 13-game winning streak, the longest in the country. Further, the Ducks had scored at least 42 points in all 13 games.

• Quotable: "It hurts, and as I told them, you'd like to have some words that would take the pain out of it, but there aren't," said Kelly. "We'll feel bad for a little bit of time and we'll bounce back from it."

Nov. 7, 2013

Stanford Stadium

• Final score: No. 6 Stanford 26, No. 2 Oregon 20

• The setup: For the second-straight year, Oregon was undefeated heading into the Stanford game. And again, the Ducks were putting up big numbers under new coach Mark Helfrich, having scored at least 50 in six of their first eight games. Stanford’s lone smudge was a loss to Utah in Salt Lake City. National championship hopes were high for both teams. Little did we know, however, that a week earlier in a win against UCLA, Mariota had injured his knee. His lack of mobility would be a major talking point after this game.

• Key play: On Oregon’s second possession, the Ducks were turned away on fourth-and-goal at the Stanford 4 when Mariota missed Bralon Addison. Early, yes, but Stanford then marched 96 yards on 12 plays, eating up 5:59 and capping the drive with a 2-yard Tyler Gaffney touchdown. He carried the ball nine times on that drive, and it set the tone for the rest of the game.

• Remember this: Much like Gerhart in 2009, Gaffney was the workhorse this time around, carrying a school-record 45 times for 157 yards and a touchdown. Though he averaged just 3.5 yards per carry, he earned every one of them.

• Quotable: "We rode him like Secretariat," said Stanford offensive coordinator Mike Bloomgren.
