Not ignoring margin of victory. To me "margin of victory", "game control", and "eye test" are all different ways of saying the same thing. It's how dominant one team was over another team.
I disagree though about ranked wins because without that there is no real way to distinguish between the "quality" of opponents. In theory the ranking reflects a team's abilities and season accomplishments. If we don't have rankings then we'd have to be relying on tradition and a program's brand, and none of us here agree with that. I'd be the first to agree that the rankings are screwed up a lot of times, but under the current system it's the best we've got.
Why use the top 25? Why not 20? Or 35? Or 15? It’s stupid. It just so happens that the top ranked team your Baylor Bears have beaten is ranked #25, so obviously that’s why you want to emphasize that. Never mind that Utah has beaten their opponents by about an average of 10 ppg more, or that Baylor had arguably the worst OOC schedule in college football. What was the record of your two G5 opponents?
