Los Angeles Chargers retired numbers: The Los Angeles Chargers are a professional American football team in the National Football League (NFL) based in the Greater Los Angeles Area.  The club began play in 1960 as a charter member of the American Football League (AFL), and spent its first season in Los Angeles before moving to San Diego in 1961.  They returned to Los Angeles in 2017.  NFL teams assign each of their players a jersey number ranging from 1 through 99.  The Chargers no longer issue four retired numbers.  As of 2010, the team's policy was to have the Chargers Hall of Fame committee evaluate candidates for a player's number to retire after the player has retired from the league after five years.  The committee consisted of Chargers Executive Vice President A. G. Spanos, Chargers public relations director Bill Johnston, San Diego Hall of Champions founder Bob Breitbard, and the presidents of the San Diego Sports Commission and the Chargers Backers Fan Club.  There are few recognized guidelines in sports regarding retiring numbers, and the NFL has no specific league policy.  "You have to have enough numbers for players to wear," said NFL spokesman Greg Aiello.  The Chargers have rarely retired numbers.  The "San Diego Union-Tribune" wrote, "The [Chargers] tend to honor their heritage haphazardly."

The Chargers will play their home games at the StubHub Center until the opening in 2020 of the Los Angeles Stadium at Hollywood Park, which they will share with the Rams.

2005 Oregon Ducks football team: In 2005, Oregon had success behind senior quarterback Kellen Clemens and a new spread offense.  During a game at Arizona, Clemens suffered a broken ankle.  At that point Oregon was 8-1 (their only loss was to #1 ranked USC 45-13, the loss was vacated in 2010), and still in the hunt for a BCS game.  Oregon won their final three games and their success led them into contention for a bid to the Fiesta Bowl.  The Ducks finished the regular season with a 10-1 record, their best finish since their Joey Harrington-led, Fiesta Bowl-winning 2001–2002 team.  They finished 5th overall in the BCS ranking system, which would in many years have been high enough to earn them a bid to a BCS Bowl.  In 2005, however, there were no at-large bids available to Oregon.  Ohio State finished just ahead of the Ducks, in 4th place, guaranteeing them one of the at-large berths (although they had an inferior 10-2 record).  Notre Dame finished 6th in the BCS, also securing a BCS bid due to a pre-existing clause in the BCS contract.  Many college football fans were outraged that two teams with worse records were selected over the Ducks.  Moreover, for the second consecutive year, the Pac-10 conference had a team that finished with a one-loss season snubbed by the BCS (the Cal Bears finished 10-1 in 2004).  It was later demonstrated that Oregon drew the highest bowl ratings in college football, calling the argument that TV ratings hurt the Ducks' BCS chances into question.  The situation (and others like it in recent years) has led to more calls for a playoff system to replace the BCS, which has received widespread criticism from college football fans.  Instead of a BCS game, they were assigned to the 2005 Holiday Bowl versus the Oklahoma Sooners.  Playing without their starting quarterback, Kellen Clemens, and combined with a strong showing from the Sooners, the Ducks fell in a close game, 17-14, finishing the season tied for the second-best in school history with a 10-1 overall record (the Southern Cal game was deemed vacated by violations in 2010).

Los Angeles Chargers Hall of Fame: The Los Angeles Chargers are a professional American football team in the National Football League (NFL) based in the Los Angeles Area.  The club began play in 1960 as a charter member of the American Football League (AFL), and spent its first season in Los Angeles before moving to San Diego in 1961.  They returned to Los Angeles in 2017.  The Chargers created their Hall of Fame in 1976.  Eligible candidates for the Hall of Fame must have been retired for at least four seasons.  Selections are made by a five-member committee chaired by Dean Spanos, Chargers vice-chairman.  As of 1992, other committee members included Bob Breitbard, founder of the San Diego Hall of Champions; Ron Fowler, president of the Greater San Diego Sports Association; Jane Rappoport, president of the Charger Backers; and Bill Johnston, the team's director of public relations.
