The point of keeping it to a 4 team playoff, and of allowing that more than 1 team from a single conference could be chosen, was so they did not have to put non elite conference champs in. It was designed precisely to enable them to put a team like OSU in if others fail to impress. A 2-loss Stanford isn't getting in just for beating USC. 1 loss B1G and SEC champs are totally in, with only 1 undefeated team left. Clemson is this year's FSU, with many predicting them to fall. Win and they are in, but lose to UNC and they are out.
UNC is kind of in our position from last year. They need to not only win, but blow out Clemson to get in over OSU. Like last year's Baylor and TCU, we are the impressive team waiting in the wings with just 1 loss. We'll be in if UNC wins but not by too much. Small window yes.
