OK, I'll try one more time for our little friend:If you have a conference with only 1-2 teams ranked in the top 25, and the rest are sprinkled somewhere between 25-100, chances are that those two teams will be able to beat the tar out of their conference opponents, on both sides of the ball, because they will be way better than them both offensively and defensively. Thus, those two teams would benefit statistically on both offense and defense, and be able to regularly post 45-10 victories.In the SEC, you usually have anywhere between 5-8 teams ranked in the top 25. Last year we ended with 5 in the top 25. This was widely considered a down year for the SEC, as Arkansas, Alabama, and South Carolina are historically better. But we'll go with five. When there are five teams in the top 25, and probably another 3 in the top 50 (three other SEC teams received votes for the AP top 25), then it's a lot more likely that the top 25 teams meet more often. In a conference with two there is really only one chance for really good in-conference competition. In a conference with 5-8 really tough teams, the stats start to even out more, because more often than not, teams are playing teams that are evenly matched on both sides of the ball. Therefore, you see a lot less 45-10 games and a lot more 35-27 games, which brings down the statistics of both teams in the tough matchups. How, you ask? Well, because the latter games are more common, teams are not able to lay monstrous 40-point thrashings on their opponents, not because they are worse than the team that plays pansy opponents, but in spite of them being far better.The reason I mentioned USC is because they play in a conference that normally only fields two teams in the top 25. Thus, they usually enjoy one of the statistically best defenses. Same with Ohio State. They ranked number 1 in total defense last year, and number 2 in 2006. Now, what happened to them in the title game the last two years? They got their asses handed to them twice in a row by SEC teams that they were statistically better than. Embarassed. Caught with their pants down. Sent crying home to mommy. I don't remember the player, but a Florida Gator said it best in 2006 when he said "Half the teams in the SEC could have come in and beaten them the way we did."Now, do you need further explanation?
