STANFORD, Calif. — Stanford coach David Shaw believes he speaks for most of the rest of the Pac-12 coaches when he talks about his lack of excitement over the fact that Oregon quarterback Justin Herbert decided to return to school rather than enter the NFL draft as a probable first-round pick.

Instead of getting to enjoy watching Herbert play on Sundays, Shaw now must contend with him on the field once again when his slumping Cardinal (0-1 Pac-12, 1-2 overall) host the 16th-ranked Ducks (2-1 overall) on Saturday.

“I think he got some bad advice to come back to school,” Shaw joked. “There are 11 other coaches in the conference who would say it. I love watching the kid play. He has a sweet stroke. We call it a repeatable motion. It’s a very smooth throwing motion. He’s such a good athlete, moves so well in the pocket, can escape the pocket, throws the deep ball with ease. You can see why he’s so highly touted by NFL scouts.”

Herbert showed that last year against Stanford when he completed 26 of 33 passes for 346 yards in a 38-31 overtime loss at home. Now he gets to face a defense that has struggled to stop big passing plays the past two weeks in losses to Southern California and Central Florida, who both lack a quarterback as capable as Herbert.

If that happens again, the Cardinal could be looking at their first three-game losing streak since 2008 — three years before Shaw took over for Jim Harbaugh.

“They got explosive plays and we didn’t,” Shaw said of last week’s 45-27 loss to Central Florida. “In three games, we’ve given up 18 plays of 20 or more yards. That’s not us. It’s missed tackles, missed alignments, letting receivers run free. We’ve got to play better from the top down on defense.”

The Ducks have been outstanding defensively the past two weeks at home against lesser opponents, allowing just nine points against Nevada and Montana and no touchdowns in the past 27 drives.

Now they have to contend with their first true road game, after losing a neutral-site game to Auburn to open the season.

“You have to understand that you’ve got to pack your toughness, your resiliency, you’ve got to pack your perseverance, all the stuff that goes with being a tough football team on the road, knowing that when you leave your home and you go do it on the road there’s the factors that are outside the football game itself,” Oregon coach Mario Cristobal said. “They can’t matter, they cannot be relevant and it requires a certain type of mindset. With young players or older players, it’s always going to be a huge point of emphasis.”

Other things to watch:

Bad memories

The Ducks have lost three straight in the series for the first time since 1995-97, and last year’s 38-31 overtime loss at home was particularly painful. Oregon led by 17 points at halftime but allowed Stanford to tie the game after C.J. Verdell lost a fumble in the final minute of regulation.

Banged-up line

The Cardinal entered the season with little depth on the offensive line, and that has been tested early this season. Star left tackle Walker Little went down with a season-ending knee injury in the opener. Guard Dylan Powell is doubtful this week, but right tackle Foster Sarell is probable to return.

Rough starts

Oregon has lost its last four conference openers, including last year’s collapse against the Cardinal. With trips still remaining to No. 22 Washington, No. 24 Arizona State and USC, as well as home games against No. 23 California and No. 19 Washington State, the Ducks can ill afford an early slip if they want to win the North.
