The media has created the 16 team league hype because it makes a playoff easier. You would basically have two 8 team leagues, then a conference championship, with the four champions squaring off and you have a make shift 8 team playoff... I see it the other way though, I think the stronger half would leave the weaker half of the conference rather than pay their bills... If the SEC goes to 14 adding Mizzu and A&M, then Auburn and Alabama will likely move East with Vandy moving West. That puts almost all the power in the East aside from LSU. I am sure some of those schools are sick of paying bills for Arkansas, Vandy and the two Mississippi schools so whats from stopping them to breaking off on their own?
The problem is in the move to 4x16, people make moves and you end up with something closer to 5x16.
We don't need conf expansion for playoffs. 5 or 6 AQ teams, 2 or 3 at large.
An 8 team playoff adds THREE games total, just 3 games played by only 4 teams out of 120. It would be so easy. Since they've already singled out 4 Bowls as better than the rest there is your first round.
