i don't think a real playoff system will happen within the next 20 years, but we can all dream can't we?
Even if all the teams have 1 loss, the BCS takes into account who beat who, who had harder schedule, what the polls thought etc...giving the teams a more or less "fair" scale.
I don't know why a lot of people hate the BCS it's the most fair thing that will happen other than playoffs and when that happens instead of complaining about who goes to the NC it will be about why one team made it instead of the other...
