I think Chizik is right, every year is it's own situation. You can't look at one year and surmise anything from it. Look at 2004. Auburn started at #17, after winning 4 games, they were #8. They would have been higher too, but in 2004, Top 5 teams weren't dropping like flies like they are this year.
I'm also still not a believer in the "state school" issue. Alabama gets their national respect because they won 82% of their games from 1958 to 1982 under the guidance of a member of the Mount Rushmore of coaches. They get the automatic respect because they have won the SEC 20 times (it's really 21 but I refuse to recognize 1972, a year in which Alabama went 7-1 and Auburn went 6-1 with a WIN OVER ALABAMA).
Clemson isn't the state school. Miami isn't a state school. Notre Dame is not a state school....it's kinda like the Vatican, it's it's own little world. You don't get respect because you're name is the University of Minnesota, you get respect because you create it by winning over a long period of time, in and out of different eras.
In 2000, Oklahoma was coming off a 7-5 season. They started the year ranked #19. By week 4, they were 4-0 and ranked #10. That's really no different than Auburn starting #17 in 2004 and being #8 by week 4.
Every year is different. If Auburn was 4-0 and the wins were La Tech, Miss State, West Virginia, and LSU, we would be ranked.
