DALLAS (AP) — College Football Playoff executive director Bill Hancock says his group isn’t even considering more than four teams in the playoff.

Hancock said Friday there are plenty of reasons why a four-team model was picked, and nothing has changed that after the first of a 12-year contract.

Larger brackets were toyed with when the playoff concept was first being put together.

Hancock says with the four-team bracket, there was no erosion of the regular season and that the experience and tradition of the bowl games was maintained. He says it worked out “really, really well” and that his group couldn’t be happier.

Some things preventing an expansion: more travel for teams and fans and where extra games would be played.
