If a Big 10 or Pac 12 team is among the BCS top four, there will be 3 semifinal games instead of 2, the third being the Rose Bowl which will still be played between the Big 10 and Pac 12 champs, regardless of where the other team is ranked. After the Rose Bowl and the other 2 semifinal games, a committee will choose which 2 of the 3 winners will play in the national title game and the other will be left out.
I thought the plus one was to keep schools from being left out, not to cause it.
