No one is ever happy. Cried about that BCS. It was the most fair but no that wasn’t good enough.
I thought the purpose of the BCS was to assure that the top two teams played each other at the end of the season. Yes, the top two in the polls, but pre-BCS it wasn’t always assured that such would be the case. At least the BCS achieved that. The playoff format is better, IMO, and maybe it could be expanded to eight teams, but given the schedules and the extra time involved, I don’t see it going beyond that. Football isn’t basketball in terms of preparation and scheduling.
