Again, there is nothing, nowhere, that says any specific conference gets automatic birds.
The new 12-team College Football Playoff field will include the five highest-ranked conference champions, which will receive automatic bids. The seven highest-ranked teams remaining will round out the 12-team format.

Who qualifies for the college football playoff?
The five highest-ranked conference champions and the next seven highest-ranked teams will earn a spot in the 12-team bracket. There is no limit to how many teams from one conference can qualify.
The rules also don't guarantee spots for certain conferences. The champions of the Big 12, SEC, ACC and Big Ten will almost certainly routinely qualify, though, along with the highest-ranked champion from the Mountain West, American Athletic Conference, Sun Belt, Mid-American Conference or Conference USA.
