Oregon holds the edge in several preseason defensive evaluations thanks to Dan Lanning’s scheme and a returning defensive line anchored by standouts like A’Mauri Washington and Bear Alexander. Multiple programs remain tightly bunched, however, with Oklahoma, Notre Dame, Indiana, Texas Tech, and Georgia each featuring experienced front sevens, productive secondaries, and coordinators with strong track records. Official rankings and analytics models show only marginal separation among these units, while Ohio State’s overall profile and depth keep it in the mix despite slightly lower defensive grades. This balance of returning production and coaching continuity across the top contenders explains the narrow implied probabilities reflected in current trader consensus.
