There was a bit of a shakeup in the BCS standings released Sunday as previously undefeated Baylor suffered a lopsided loss to Oklahoma State, 49-17, to drop to sixth place.

Oregon lost its second game of the season, to Arizona, 42-16, to plummet from No. 5 to No. 13 in the standings.

The top three teams in the BCS standings – Alabama, Florida State and Ohio State – remained in place and are the only undefeated teams in BCS automatic qualifying conferences (ACC, Big 12, AAC, Big Ten, Pac-12 and SEC.)

The Buckeyes (.9200 BCS average) have a solid lead on Auburn (.8326) and Missouri (.8077), both of which entered the top five this week.

Auburn had a bye week after rallying for a thrilling, 43-38, victory over Georgia on Nov. 16. Missouri topped Ole Miss 24-10 Saturday.

Undefeated Northern Illinois and Fresno State vaulted to 14th and 16th place, respectively, and are both fighting for one non-AQ berth. For teams in non-AQ conferences to receive an automatic berth, they have to finish in the top 12 of the last BCS standings or ranked in the top 16 ahead of an AQ-conference champion.

The Bowl Championship Series, which features four bowl games and the national championship game, is in its last season. The four-team College Football Playoff will debut next year.
