[QUOTE="ibeattetris, post: 651529, member: 1175"] I feel like their are two ways to determine rank. This method is strength based and is more about who is more likely to win. So starting top to bottom, you could say the higher in the list, the more likely that team is to beat the teams below them. The other way of ranking is more similar to your approach and that is based on wins. This ranking is more about "how good of a season is the team having". I believe for bowls/post season this is the best approach, but that doesn't mean I don't find strength based metrics interesting. If a team wins 13 games by 1 point, they obviously are very good. If another team was 11-2 where the 11 wins were by 30 and the two losses were by 1, I would say the 11-2 team was a stronger team, but that the 13-0 had a better season (we will assume same strength of schedule just to make the example easier). As I mentioned earlier, there are a ton of these ranking algorithms. If you are interested in one that only cares about wins and losses (and includes a SOS metric) than this is probably the one you would be interested in: [URL]http://www.cpiratings.com/top25.html[/URL] It calculates opponents win % and opponents opponents win % to determine SOS.
