Big Ten Commissioner Jim Delany says BCS officials are narrowing the field of possible changes to college football's postseason and the Rose Bowl is not standing in the way of progress.
Delany has been meeting with his fellow commissioners, Notre Dame's athletic director and other college football officials working on overhauling the Bowl Championship Series.
Among the options being discussed Wednesday is a four-team playoff that could be held separate from the bowls.
Delany says there is "pretty high expectation that there's going to be change."
He also says he wants the group to proceed with caution.
He says: "I just want to make sure that the changes that we make are evolutionary. That they support the regular season. That ... from a Rose Bowl perspective, that they sustain that tradition."
