chicolby if you expand to 8 teams, several 2 loss teams will get in, this is not debatable. May not bother you, but allow me to expand...
If people are disgusted with ESPN's love affair with the SEC now, wait until you let 2 loss teams in. SEC will have 3 teams in every couple of years. If you are saying the best teams should get in, period, then you have to remove the number of teams that can qualify regardless of conference affiliation. Can't say "put the best teams in, period", then limit conferences to 2 teams each. So you think about how many times the SEC would get at least 2, and many years 3 teams in going forward. It would happen. It would become the SEC invitational.
