Oregon State's Sean Mannion and Oregon's Marcus Mariota are two strikingly different quarterbacks who have both seen their seasons take a frustrating downturn.
The two will play with mostly pride on the line - and perhaps redemption - when the No. 12 Ducks host the Beavers in the annual Civil War rivalry game on Friday afternoon.
Mariota, who took a hard hit to the head in last weekend's 42-16 loss to Arizona, says he has passed all of the concussion tests and will play. But there are still lingering questions about the health of his left knee.
Mannion's issue seems to be confidence after throwing 10 interceptions in Oregon State's last three games - all losses. He threw three in the Beavers' 69-27 loss to Washington last weekend.
