Ohio State, Louisville move up behind Alabama in AP poll

— -- Ohio State and Louisville moved up behind No. 1 Alabama in The Associated Press college football poll after the most surprising Saturday of the season gave the rankings a major makeover.

Three of the top four (Michigan, Clemson and Washington), five of the top 10 and seven teams overall in last week's rankings lost to unranked opponents.

On Sunday, Alabama was a unanimous No. 1 for the first time this season, receiving all 61 votes. Ohio State is No. 2, a season best for the Buckeyes, and Louisville is No. 3, matching its best ranking ever.

No. 4 Michigan and No. 5 Clemson each dropped two spots and No. 7 Washington fell three after losing for the first time. Wisconsin moved up a spot to No. 6.

The only teams that held onto the spots in the Top 25 that they had last week were the only unbeatens left in the FBS: the top-ranked Crimson Tide and No. 14 Western Michigan. The Crimson Tide have been No. 1 since the preseason.

The Crimson Tide is the first unanimous No. 1 since Ohio State on Sept. 8, 2015.

No. 12 Colorado and No. 13 Oklahoma State each moved up four spots.? Baylor is also out of the rankings for the first time this season.
