I mean, I know these last 10 days have seemed like an eternity, but we held Ohio flipping State to 21 points and less than 400 total yards.
That's a far more potent offense.
Also can't say I agree with your assertion that their OL will be certainly better than Cal. UNC is 111th in QB sack percentage. And while it's better than Cal's currently....Cal played us, which brought the ranking down significantly, while UNC has played the likes of Appalachian State, FAMU and Georgia State.
I'd say both are equally terrible, and UNC may be potentially worse.
