Oregon, Ohio State, Georgia, Miami top 1st CFP rankings - ESPN

Unbeaten Oregon is the No. 1 team in the first rankings released by the College Football Playoff selection committee on Tuesday.

The Ducks were followed by Ohio State, Georgia, Miami and Texas in the top five.

Penn State, Tennessee, Indiana, BYU, Notre Dame, Alabama and Boise State round out the top 12, which would compete in the newly expanded playoff at season's end.

Because the top four seeds must be conference champions under the new CFP format, Oregon (Big Ten), Georgia (SEC), Miami (ACC) and BYU (Big 12) would receive first-round byes if the initial rankings were used for the 12-team bracket.

The first-round games would look like this: Boise State at Ohio State, Alabama at Texas, Notre Dame at Penn State and Indiana at Tennessee.

Ohio State remains the consensus betting favorite to win the national title at ESPN BET at +325, slightly ahead of Georgia and Oregon, both at +400. There were no significant changes to the odds to win the national title odds after the rankings were released.

The SEC and Big Ten each had four teams in the top 12. Undefeated BYU is the lone Big 12 program in the top 12, and unbeaten Miami is the only ACC team in the top 12 after Clemson suffered its second loss last week, to Louisville at home.

Boise State, whose only defeat of the season was at Oregon on Sept. 7, was the highest-ranked team from a Group of Five conference.

SMU was No. 13 in the selection committee's rankings, followed by Texas A&M, LSU, Ole Miss, Iowa State, Pittsburgh, Kansas State and Colorado.

Washington State, Louisville, Clemson, Missouri and unbeaten Army rounded out the top 25.

After 10 years with a four-team playoff, CFP selection committee chairman Warde Manuel said the group's mission hasn't changed with a bigger
