Conference commissioners are considering the possibility of adding another game to be part of the semifinal rotation for the new college football playoff. The postseason plan approved by university presidents in June called for the national semifinals to rotate among six bowl sites. The years those sites do not host semifinals, they would be marquee bowl games, involving other highly ranked teams. There are numerous details still be worked before the format is implemented in 2014, including the composition of the selection committee that will pick the playoff participants, site of the first championship game and revenue distribution. And now it seems like the plan might be tweaked to give teams that don't make the playoff more chances to play in high revenue games.
