A team shouldn't move into or be moved out of (or be excluded from moving into) the top 4 just based on whether or not they played in a CCG. This isn't a computer ranking scenario where suddenly a new highly rated opponent changes some computations. These are humans that have decided that a certain team is top 4, other teams are not, which should mean that those teams should have to do something that makes the committee change their minds (and not playing is not that something). It's not enough to say "well, Ohio State won an extra game and Mississippi State didn't, so we have to move one out and the other in," or "TCU and Baylor didn't play a CCG, so they'll just have to stay where they are (on the outside) and we'll move other teams around them." It should be "a team on the outside won an extra game. And? Are they or are they not better than a team in the top 4? Why should what this team did this week change our mind about what the top 4 team has done all year?"
Frankly, I don't buy it. The committee is certainly free to reassess their prior judgments, but it shouldn't be considered a mere formality that they will, as there's really no reason they should unless a team actually is more impressive.
Mississippi State is 4 right now. If Mississippi State is impressive in their next 2 games, then TCU, Baylor, or Ohio State should have to be much more impressive in order to move up, and the CCG (for tMCU) might help that, but it's no given.
