I also have concern about “STUDENT-Athletes” missing more class time due to an expanded season an 8 game play-off would entail. The NFL feeder system leading to the big bucks only applies to a few of the many college athletes. Top 4 seems to work. Even in basketball where they take the top 64 or 66, we still have complainers who were on the bubble and got left out.
You are talking about one more game that 2 teams play in the end to have a real championship.
