You are probably right. The challenge is, some do this to predict how it ends up, and some, myself included, do it based on things now.
So, for exampl, I think it highly likely OSU would get whipped by many of these teams if the played tomorrow, because serious lack of experience at QB. But it is not uncommon for that to change after the season progresses, for that position to improve dramatically and therefore the team is much tougher to beat.
This year, especially in the west, should be a riot to watch.
