Ohio States Replaces L.S.U. Atop College Football Playoff Rankings

Ohio State jumped past L.S.U. to No. 1 in the College Football Playoff rankings with two weeks left to go before Selection Sunday.

L.S.U. slipped to second on Tuesday night and Clemson remained third, while Georgia held on at No. 4. If playoff history holds form, three of those top four teams will reach the semifinals.

Alabama remained No. 5 in the selection committee’s third rankings, with Utah moving up a spot to No. 6. The Utes are the only Pac-12 team in the top 10 after Oregon dropped eight spots to 14th.

Oklahoma is seventh, followed by Minnesota, Baylor and Penn State.

In each of the first five years of the playoff, three of the top four teams in the rankings heading into rivalry weekend reached the semifinals, including the No. 1 team every time.

Now that spot belongs to Ohio State, which the committee chairman, Ron Mullens, has continually referred to as a complete team.

“Competing consistently and really highly ranked on offense and defense. Performing at a high level on both,” Mullens said of Ohio State, which currently leads the nation in scoring and points allowed.

The Buckeyes beat Penn State last weekend, 28-17, for their third victory of the season against a team currently ranked. They also beat No. 12 Wisconsin and No. 18 Cincinnati. L.S.U. has beaten No. 5 Alabama, No. 11 Florida and No. 15 Auburn.
