I disagree with this premise.
IMO, beating Stanford by 21 at home > beating Va Tech by 3 on the road (if for no other reason than the basic assumption that home field advantage is only worth 3 points).
ASU & OSU are about equal (as evidenced by the Beavs 3-point victory over the Devils in Corvallis), so it should follow that an 11 point victory @ ASU is approximately equivalent to a 13 point home victory over OSU. No advantage here either way.
After that, BSU's resume has 3 teams that are bottom-25 nationally; UO's does as well, but it also has the 35-point road-win over an SEC team. So, cumulatively, I would say that UO's schedule has been better than BSU's by virtue of the Tennessee game, and their overall performance has been better based on the nature of their victory over Stanford (dominance, as compared to BSU's nail-biter over VT).
