Oregon Ducks fans have dreams that this will be the year they finally win the national championship. Expectations are high for the Ducks to do just that, and they are considered among the top contenders with one of the most talented returning rosters, which features star quarterback and Heisman Trophy contender Dante Moore. Some believe that with all this returning talent, including the addition of talented newcomers from the transfer portal and recruiting, 2026 will finally be the year the Ducks lift the national championship trophy.

While the concerns include playing under two new coordinators and having a new-look offensive line, there is one concern that isn’t getting as much attention as it deserves. How Oregon's Defense Performs in Big GamesOregon defensive coordinator Chris Hampton speaks during a press conference on March 14, 2026, in Eugene, Oregon. | USA TODAY Network via Reuters ConnectWhile the Ducks' defense has made major strides in its four-year tenure under coach Dan Lanning, its performance at times led to major losses for Oregon in past seasons, especially in its last two appearances in the College Football Playoff. With the Ducks entering the season as a national championship contender and one of the teams with the best odds to make the CFP out of the Big Ten, defensive play must not be overlooked in these key matchups. In Oregon’s last two CFP losses, which both came to the eventual national champions, the Ohio State Buckeyes (2024) and Indiana Hoosiers (2025), the Ducks' defense allowed 40-plus points in both games. The last thing Ducks fans want to happen this season is for their defense to fall flat when it matters most and be eliminated by another team that goes on to win the national championship. Following the departure of Tosh Lupoi to become the new coach of the California Golden Bears, Chris Hampton steps in as the Ducks' new defensive coordinator and faces massive expectations.Key Defensive Players Oregon Will Rely On Nov 29, 2025; Minneapolis, Minnesota, USA; Minnesota Golden Gophers defensive back Koi Perich (3) warms up before the game against the Wisconsin Badgers at Huntington Bank Stadium.

Two of those players are in the Ducks' secondary, including sophomore star cornerback Brandon Finney Jr. and Minnesota Golden Gophers transfer safety Koi Perich. Finney Jr. rose to stardom for his performance in the Ducks' 23-0 shutout win over the Texas Tech Red Raiders in the CFP Quarterfinal at the Orange Bowl, in which he recorded six total tackles, two interceptions, and one fumble recovery.
