I think most people agree with this. The bowl attendance and ratings are going to drop significantly because all anyone will care about is the playoffs. It will be 8 teams sooner than later.
I posted that in October 2014. I am surprised it took this long to start seriously looking at expanding the playoffs. The bowls' have deep hooks into the administrations at the P5 schools.
I did not appreciate at the time how much a 4 team playoff would concentrate talent in college football. With only 4 playoff spots, either a top player is on one of a handful of teams, or he is probably not getting in the playoffs. A 4 team playoff means that maybe 8 to 10 teams have a realistic shot of making the playoff any given season. An 8 team playoff probably expands that range to 20 to 30 teams.
Every Athletic Director in the P5 is an idiot if he/she does not look at what happened to the G5 schools and know that some version of that could happen to their school. How long are Clemson or tOSU or Texas/Oklahoma going to carry their leagues before demanding a bigger and bigger share of the pie?
Greater access to the playoffs is better for everyone, especially the non-Clemson/Alabama P5 schools. "Greater access" to the playoffs really means 4 more P5 schools going to the playoffs. That is a win for everybody (that matters).
