I'm picking OSU because while they're very similar teams in some ways, I feel like OSU would have more range in their play-calling. You couldn't run on FSU, but you could run on OSU (see UM game). But I feel like FSU would still want to pass a certain amount, even if the run game was rolling. OSU would run-run-run if it was working or be able to pass more if it wasn't.
99% of teams run more than they pass, and both of these did, but FSU felt obligated to pass, which may be a problem vs such a tough opponent.
That may be a weird reason, and I don't think I've ever used it before, but I think it's true.
