I've created my poll for week 4. Here's my methodology.
First, I considered every team in FBS with no more then 1 loss. I think it's too early to consider any 2-loss teams like FSU, Washington, or Texas Tech.
Looking at each team's wins and losses and considering their opponents, I ranked each team within their own group, the 6 BCS conferences and everybody else. Here are the 36 teams I considered ranking after that:
SEC......Pac.10....Big.12....Big.10....ACC.....Big .East..Others
Alab.....USC.......Texas.....Iowa......VaTech..Cin cy.....Houston
Florida..Oregon....Oklahoma..tOSU......Miami...USF .......Boise
LSU......UCLA......Mizzou....TSUN......GaTech..... .......TCU
Auburn...Cal.......Kansas....Wiscy.....N.Car...... .......BYU
Georgia..Ariz......Okla.St...Penn.St.............. .......Utah
S.Car....Stan......Neb............................ .......N.D
Ole.Miss
Then I started ranking teams, based solely on what's happened on the field so far this year. Preseason polls weren't factored in, last year's results weren't factored in, what I expect to happen the rest of the year wasn't factored in, and who I think would win on a neutral field wasn't factored in. Also, no polls from last week were factored in; teams with losses or with good wins weren't moved a certain number of spots, they were slotted accoriding to my evaluation of season-to-date results.
Head-to-head was considered. Chains of an undefeated team and a bunch of 1-loss teams were looked for, here's one: Houston-Okla St-Ga-S.Car-OleMiss. Two chains that existed last week were broken when teams near the beginning of the chain lost: Miami-FSU-BYU-Oklahoma no longer applies, so each team is evaluated on overall results. Also the LSU-Washington-USC-tOSU chain was broken.
The severity of a loss was also factored in, So although USC beat tOSU, their loss to now-unranked Washington is more damaging than tOSU's loss to USC. Combined with 2 straight shutouts, I have tOSU ahead of USC.
Here's what I came up with:
01. Alabama
02. Florida
03. Texas
04. Iowa
05. Houston (their schedule will prevent them rising to the top-2)
06. LSU
07. Va Tech (best results of the 1-loss teams)
08. tOSU
09. Oklahoma (BYU loss is looking worse with FSU results)
10. USC
11. Cincinnati
12. Boise St
13. Auburn
14. Mizzou
15. Kansas
16. Okla St
17. Oregon
18. TCU
19. USF
20. UCLA
21. Miami (they were my #1 last week)
22. TSUN
23. Georgia
24. BYU (beating Oklahoma carries weight)
25. S. Carolina
Cal and Penn State dropped from the top 10 to unranked, since Cal got hammered and hasn't beaten a ranked team, and Penn State also hasn't beaten anybody with a pulse.
