I agree that a 4-team playoff is insufficient. But it is better than the BCS, or the AP/UPI/Coaches’ poll champions of old.
But one needs to discuss this as they way things are, rather than the way one would like them to be. An undefeated team in a lesser conference without a big win against a Power-5 team is not going to rank well against 1- (or even 2- loss) Power-5 teams. That is why the GA Tech cancellation hurt UCF.
But the Auburn game corrects that deficiency.
Both Miami and UCF had to reschedule with Georgia tech. Miami got that available date. Tech’s other opening was already a scheduled game for ucf.
But, none of this changes the fact that ucf beat the team that beat both of the remaining teams in the playoffs.
