The College Football Playoff selection committee announced that nine of its 13 members have been recused from voting for certain schools.

Mike Gould (Air Force); Jeff Long (Arkansas); Dan Radakovich (Clemson); Archie Manning (Mississippi); Tom Osborne (Nebraska); Pat Haden (USC); Condoleezza Rice (Stanford); Oliver Luck (West Virginia); and Barry Alvarez (Wisconsin) were recused.

Five of the members are current athletic directors, including Long (the committee chair), Radakovich, Haden, Luck and Alvarez. Rice is a professor at Stanford and Gould is the former superintendent of the Air Force Academy.

Committee member Tyrone Willingham was not on the recusal list, despite formerly coaching Washington, Notre Dame and Stanford. The committee's executive director, Bill Hancock, said Willingham was not on the list because he is not currently associated with either of the schools.

"If you look at the recusal policy, he's not compensated by any school," Hancock said. "He doesn't have any relatives who are compensated by a school, nor does he provide professional services to a school."

Recused committee members are only allowed to answer factual questions about their respective school affiliations, but are not allowed in the meeting room during any deliberations about that team's selection or seeding.

The selection committee will rank 25 teams throughout the season. They will select the four playoff teams, which includes placing them in the contract bowls (Rose, Orange and Sugar) and finishing with the Cotton, Fiesta and Peach bowls.

The Rose and Sugar bowls are this season's playoff semifinals.

The committee will determine the top 25 by going through seven rounds of ballots, not including a possible re-vote if at least three committee members believe another group of teams should be considered. Individual ballots, which will not be made public this season, will be compiled into a composite ranking.

"We looked at previous years, and there was spirited debate," Hancock said. "We really dived into some teams' resumes and compared them in a very extensive way."

Conference championships, strength of schedule, head-to-head competition, comparative outcomes of common opponents and key injuries are among the factors the committee will consider when deciding on the four playoff teams.

The committee's first playoff rankings will be announced on Oct. 28.
