You and I think about this stuff way differently. The Stanford team that ended the season ranked #1 will always be #1 for that season. That is how we honor that makeup of players and coaches and circumstances that led to their title run. This is a new season, the teams aren't the same and the slate is clean. Thus, in my mind, Stanford will have to earn their ranking as much as any other team. To me, this is more about forecasting than anything else. It's trying to predict the outcomes and has nothing to do with any honor system.
So, with your logic should the rest of the top 25 stay static until this season. I mean, Arizona earned the #2 spot, so should the polls honor it in the preseason polls despite any other factors?
