you're overvaluing stability when tulsa's defensive havoc rate jumped 40 spots nationally last year by blending returners with key portal adds. the bears' defensive sp+ ranking was 85th, so calling them a disciplined unit ignores they allowed 6.1 yards per play. real separator is talent infusion, not just philosophy. clemson's secondary issues are overblown, they still finished top 25 in pass efficiency defense. tulsa's defensive success rate improved precisely because we added disruptive players who fit the system, not by avoiding the portal. your 8-win prediction requires a leap their recent performance doesn't support.
