Unfortunately, there really wouldn’t be any chaos. At this point, USC is the only team that would fall out since you would have four one-loss teams. TCU, Michigan, Georgia, Ohio State would be your 4 with the order being decided by how bad each team lost in their CCG.
There isn’t a chance that 4 loss Purdue or 3 loss Kansas State/Utah get in. It would be fun to see the committee try to justify 3 loss LSU (who lost to 5-7 A&M) just because they beat Georgia but I don’t see it happening. So you are really just down to the 2 loss ACC champ and Ohio State as being able to move into the top 4.
