“The more I think about it, the more opportunity for improvement I see,” he said.

Scott said that any variation of a two-team playoff would not be enough to mute the critics of the current system and that an eight-team playoff would be difficult to fit into the academic calendar, a priority for Pac-12 leaders. He would not say directly that he favors a four-team playoff, but his view appears to be in line with many of the top B.C.S. officials.

As for the potential playoff format, Scott agreed with the position of the Big Ten, first reported by The Chicago Tribune, which favored home sites for the semifinal games and a neutral site for the championship game. After a number of discussions with the N.F.L., Scott said, following its model made sense.

“There’s a reason that in the N.F.L. they only play the Super Bowl as a neutral-site game,” he said. “There’s a reason they play playoffs and A.F.C. and N.F.C. championships with home hosting.”

Scott added that the Pac-12 chose a campus-hosting model for its title game because he felt it would create the best atmosphere. Fans, he said, would be unlikely to travel to two neutral sites in 10 days.

“If the N.F.L. thought that they could support that model, they would,” he said.

As for determining the final four teams, Scott said a notion that Roy Kramer, a former Southeastern Conference commissioner, expressed to CBSSports.com last week “resonated with me.” To keep the integrity of the regular season and the conference championship games, Kramer said, all of the teams in the playoff should be conference champions.
