College football's Top 25 is an interesting animal. There are plenty of unwritten rules that voters seem to follow, even though it may leave some deserving teams out of the first few weeks' rankings.
For instance, a reigning national champion is generally going to stay in the top slot unless it loses a game. That one at least makes some sense, but it isn't always enforced. On the other hand, teams that start in the Top 25 are also kept there until they suffer at least one loss, even if another undefeated team has actually looked better during the first few games.
Presumably, the thought process is that the rankings will shake out by the end of the season. However, what if the voters weren't allowed to submit a poll until after Week 5 concluded? How would that look?
It would still have some heavy bias toward the BCS-AQ conferences, but it would look considerably different from the current Week 6 edition. Here is the prediction of what the Top 25 would look like right now if voters had just submitted their first ballots of the season.
