easy, happens every year:
the mid level sec teams are always over-ranked to start the season
then the never play anyone (esp on the road) and always beat those nobodys,
then when they play each other in conf, the loser has a "good loss" and doesnt drop in the polls, while the winner has a "good win" and moves up in the polls.
it's a cycle that happens evey year and makes the mid level teams and the conf look better than it actually is...
If you were correct, then the SEC would not be strong in Bowls. An example of this is ND. Year after year they are invited to bowls they don't deserve to be in, thus their massive bowl losing streak. Last year, SEC played in 9 bowls and finished with a 6-3 record.
BTW, I bet you would actually be able to provide useful info to the forum if you took the energy you put into arguing how bad the SEC is, and used it to cap some games and post some unbiased info and opinions. Just sayin'
