Nebraska head coach Scott Frost is among the people suggesting that the event go to eight teams.Speaking last week, Frost said he has an idea for the way the event should be structured. Frost believes that the five ‘Power 5’ conference winners should get auto-bids, while the final three teams should be at-large selections.Here’s what Frost had to say:“I’m a proponent of an eight-team playoff, I have been. I’ll keep this short for you. It needs to be the five major college football champions and three at-large.I think that makes the most sense. Then a team like UCF this year or last year would have a chance to go compete for it.Take the case of the Big Ten this year. If Northwestern would have beat Ohio State in the championship game and win the Big Ten then they deserve to be in. Ohio State would probably deserve to be in too at 11-2, or 12-1.I think that gives you the best chance to solve it on the field. Any sport where you solve it on the field instead of in the committee room is a better sport to me.”Some believes that six teams – not eight teams – is the right number. In that scenario, the top two seeds would have byes.It’s unclear if and when the playoff will expand, but there is clearly support for it.
