Of note, a CC is the criterion and not how it was attained. Here is the Q/A on the subject:
Q: One thing you said on TV that I'd like some clarification about, you said special consideration will be given to championships that are won on championship weekend. Does that also refer to a championship that might be won outside a conference playoff?
A: No, I'm talking – I'm sorry, I was talking about all Conference Championships, whether that was played in a playoff or whether that was determined by the conference.
He also said thast only CFP rankings are considered when looking at a team whose opponent may have been ranked sat the time of the game but is no longer ranked. Teams get credit for playing a previously ranked (CFP) team.The committee does not give marks for playing opponents ranked in any other poll.
