Nebraska has one of the few offenses that could keep up with Oregon in a shootout. I wouldn't cringe at that matchup.
To answer your question, no, the only people who would think that in-depth about that issue would be Ohio State fans. I'd like to think Ohio State would get credit (e.g., "Hey, Nebraska almost beat Oregon, and Ohio State waxed Nebraska, so I bet Ohio State might beat Oregon"), but the reality is they wouldn't. If it even got that far in a dialogue, there are about 17 different excuses someone could give as to why you couldn't extrapolate Ohio State's merits based on a game that didn't include them.
