Context paragraphs:
2010 NCAA Division I FBS football rankings: Three human polls and one formula ranking make up the 2010 NCAA Division I FBS (Football Bowl Subdivision) football rankings, in addition to various publications' preseason polls.  Unlike most sports, college football's governing body, the NCAA, does not bestow a national championship title.  That title is bestowed by one or more of four different polling agencies.  There are two main weekly polls that begin in the preseason: the AP Poll and the Coaches' Poll.  Two additional polls are released midway through the season; the Harris Interactive Poll is released after the sixth week of the season and the Bowl Championship Series (BCS) Standings is released after the seventh week.  The Harris Poll and Coaches Poll are factors in the BCS Standings.  At the end of the season, on Sunday, December 5, 2010, the BCS Standings determines who plays in the BCS bowl games as well as the 2011 BCS National Championship Game on January 10, 2011 at the University of Phoenix Stadium in Glendale, Arizona.

Bowl Championship Series controversies: The Bowl Championship Series (BCS) was a selection system designed, through polls and computer statistics, to determine a No. 1 and No. 2 ranked team in the NCAA Division I Football Bowl Subdivision (FBS).  After the final polls, the two top teams were chosen to play in the BCS National Championship Game which determined the BCS national champion team, but not the champion team for independent voting systems (most notably the AP Poll).  This format was intended to be "bowl-centered" rather than a traditional playoff system, since numerous FBS Conferences have expressed their unwillingness to participate in a play-off system.  However, due to the unique and often esoteric nature of the BCS format, there had been controversy as to which two teams should play for the national championship and which teams should play in the four other BCS bowl games (Fiesta Bowl, Orange Bowl, Rose Bowl, and Sugar Bowl).  In this selection process, the BCS was often criticized for conference favoritism, its inequality of access for teams in non-Automatic Qualifying (non-AQ) Conferences (most likely due to perceived strength of schedule), and perceived monopolistic, "profit-centered" motives.  In terms of this last concern, Congress has explored the possibility on more than one occasion of holding hearings to determine the legality of the BCS under the terms of the Sherman Anti-Trust Act, and the United States Justice Department has also periodically announced interest in investigating the BCS for similar reasons.

1999 Fiesta Bowl: The 1999 Fiesta Bowl, the designated BCS National Championship Game for the 1998 season, was played on January 4, 1999, in Tempe, Arizona at Sun Devil Stadium.  The teams were the Tennessee Volunteers and Florida State Seminoles.  Tennessee entered the contest undefeated and number one in the major polls.  Florida State sophomore QB Chris Weinke was injured in Florida State's final ACC game of the regular season and did not participate in the championship game.  Ultimately, Tennessee won their sixth National Championship after a gap of forty-seven years by beating the Seminoles by a score of 23–16.  The game was the first BCS National Championship.

The team also won the AP title for the second year in a row.  It was the Trojans' first undisputed national championship since 1972, and the second time a team had gone wire-to-wire, with the Trojans holding the number 1 spot in the polls all season.  The team was coached by Pete Carroll in his fourth year with the Trojans, and played their home games in the Los Angeles Memorial Coliseum.

2009 Fiesta Bowl: The 2009 Tostitos Fiesta Bowl game was a post-season college football bowl game between the Ohio State Buckeyes and the Texas Longhorns on Monday, January 5, 2009, at University of Phoenix Stadium in Glendale, Arizona.  Texas participated in the Fiesta Bowl because the Big 12 champion University of Oklahoma Sooners were participating in the 2009 BCS National Championship Game; however the bowl kept its ties to the Big 12 by selecting the Longhorns, who did not play in the championship game as they beat Oklahoma in the Red River Rivalry, 45-35, then lost to Texas Tech and Texas Tech in turn lost to Oklahoma and dictated that a tiebreaker would decide that the highest BCS ranked team for the Big 12 South the week of November 28, 2008 would be in the title game.  The Buckeyes were chosen as an at-large school as co-champions of the Big Ten Conference, having lost the right to play in the Rose Bowl due to a 13-6 loss to Penn State on October 25.

List of Oregon Ducks bowl games: The Oregon Ducks college football team competes as part of the NCAA Division I Football Bowl Subdivision (FBS), representing the University of Oregon in the North Division of the Pac-12 Conference (Pac-12).

From 2009 to 2012, Chip Kelly was Oregon's head coach, and led the Ducks to BCS bowl appearances in each of his four seasons at Oregon.  After losses in both the 2010 Rose Bowl and the 2011 BCS National Championship Game, Kelly led the Ducks to a victory in the 2012 Rose Bowl over Wisconsin and in the 2013 Fiesta Bowl over Kansas State.
