From almost the exact moment college football's leaders decided to institute a four-team playoff for the national championship, talk about a future expansion of the tournament to eight or 16 teams has been a constant.

Three years into the current system, though, College Football Playoff executive director Bill Hancock says there have been no discussions at the highest level about adding teams to the fold.

"There is no talk about expansion of the field," Hancock told reporters Wednesday during an appearance at SEC Media Days. "Why monkey with a good thing?"

Hancock noted that there are nine years remaining on the contract for the current setup, which has produced three different national champions in Ohio State, Alabama and Clemson.

Though each year has brought, and will continue to bring, the inevitable griping from the teams that fall fifth and sixth in the CFP committee's final rankings and thus miss out on the semifinals, Hancock said the existing format provides the best balance between crowning a worthy champion and ensuring the other FBS teams can still find a measure of satisfaction.

"Four lets us keep the focus on the regular season," he said.
