The AP preseason Top 25 is a time honored tradition. We love college football so much that we can't wait until teams have actually started playing to begin ranking them.
This system is not without flaws. Voters are forced to speculate on how inexperienced college players will adjust to the big stage. This is not the NFL, and it is more difficult to predict how a player will adjust to an unfamiliar situation.
The Top 25 does not go through a season without change. There are several teams in the Top 25 who have first-round picks to replace at key positions. Underachieving in the first two weeks could mark a short stay in the rankings, especially for teams closer to the bottom of the 25-team list.
There is less margin for error at the bottom. An underwhelming performance against a cupcake or worse, a loss, could send these teams tumbling from the rankings.
So, which teams on the list now will be gone by the time October rolls around?
