Everyone remembers the two wheel routes that burned Oregon in the third quarter. This was made possible by the WRs before anything else. Same route, but two different plays. On the first one, Solomon set up in the pocket looking right. Hill and Grant were on the right. Snap, set, throw, big gain. Oregon accounted for all of the WRs and still knew they’d left themselves open to the run because they couldn’t load up the box. As soon as they recognized that it was a pass they completely forgot about TJG.
Let’s look at the second one for the TD. This is something that RichRod set Oregon up for all season long. How many times has he sent that rolling pocket and the ball goes towards the rollout? This time he used that film to his advantage.

Typical four wide set for Arizona. See that boundary side safety? He’s about to guess right… at least for a second. Right before the snap he rolls towards the right side of the field. Hill and Johnson are left in 1-on-1 coverage. There’s three on the field side.

As they’ve done so many times before, they roll the pocket right. The safety who rolled over is now heading right into the action. They’ve got three guys covering that side of the field plus another one set to control the gap so Solomon can’t run. 10 of Oregon’s players are in the frame and the 11th is off chasing Hill. All of the WRs are covered to some extent. But once they recognize the rollout they forget Wilson is there. Then Solomon stops and turns.

Oregon has covered all of the receivers and they’ve run themselves out of the play in the process. The safety on that side of the field was screwed the second he stepped to his left. No one is within 15 yards of Wilson. Six points and a lead they’ll never give away. The Ducks played that rolling pocket just like they'd seen on film and then the Cats reeled them in easily.
If you look again at the pre-snap cover, there’s a lot problems that Oregon has to account for. They have to try to cover everyone. If Arizona decides to run it, they’ve got the numbers to do it. Plus Johnson was gone so fast on that route that the slot corner was toast. A receiver was open in the flat. This is why the WR corps is so deadly. They didn’t even touch the ball on either of those wheel routes and they still made the plays work. Again, who do you cover? These are the kind of weapons that Rodriguez has to work with, and if Solomon is making the throws Arizona will run riot on you.
