You are that delusional vol fan. You're mistaking passion & optimism for common sense. In fact I would be willing to say majority of this board would not call your ridiculous prediction .. wisdom. This happens every off season, regardless of the previous season we had, fans talk themselves into 10+ win seasons.
We got smoked by Florida, played a Tua-less Bama, and beat 2 below average teams in MSU, Vandy. The fact you're comparing our team, specifically our defense, to arguably the greatest college football team of all time is laughable. Did our defense play considerably better last year than they have in probably the last 10 years? YES. Are they going to take another step forward? TBD. Are they going to for sure shutdown/stop OU? LOL no.
OU lost Hurts & Lamb, I'm aware of that. Are you familiar with who else they have? They are absolutely loaded at WR. And they have a QB in Rattler that can sling the pigskin all over the field with a full off season ahead of him. Why would you think we would just automatically shut them down? I'm not trying to change your mind.. I'm just pointing out how delusional you are.
