I think the worst case scenario for the BCS would be for Auburn and Oregon to lose a game. And for LSU, Wisconsin, Ohio State, Michigan State, Nebraska or Okie State, and Stanford to all win out. Then you would have TCU and Boise with no losses, and LSU, Auburn, Oregon, Stanford, Wisconsin, Michigan State, Ohio State, Nebraska or Okie State, all with 1 loss.
As much as a 1 loss SEC or Big 10 team jumping an undefeated TCU or BSU screams for a playoff system, so does the 2 of them playing each other. Should the 2 of them get in over a 1 loss SEC team, especially if both get in over a 1 loss SEC team that would be a joke. Neither of them play anywhere near the schedule that teams from the SEC, Big 10, or Big 12 play.
If Cam is ineligible, the AU can't be in the NC, as their wins would be vacated. That scenario "could" actually be good for LSU if Oregon loses a game. The NC would be played between a TCU or Boisy and LSU. BUT ... I don't think it is wise to linger over such speculation ... Cam's not going to be deemed ineligible before the NC.
that would most certainly bring out the bias in the Human vote. Based on the media tone, I say you can probably scratch LSU off that list.
