Sedan Cambrai Football Club are an Australian rules football club based in the Murraylands region of South Australia that were initially formed in 1922 as Cambrai Sedan, a merger between the Sedan Football Club and the Cambrai Football Club.
 The club initially participated in the Murray Ranges Football Association, temporarily shifting for one season (1925) to the Murray River Football Association before returning and in 1930 were renamed to Sedan Cambrai.
 In 1936 the club went into recess until after World War II, when in 1947 it reformed and joined the Barossa & Murray Valley Football Association, lasting for four seasons before going into recess again in 1951.
 In 1955 the club reformed again and returned to the Barossa & Murray Valley Association.
 Sedan Cambrai had a short affiliation with the Gawler and District Football Association's AII competition from 1957-1958 before shifting to the Torrens Valley Football Association AII competition in 1959.
 When the TVFA merged into the new Hills Football League in 1967, Sedan Cambrai joined the Northern Division and then were placed in the Division 2 competition when the Hills League was restructured in 1972.
 In 1975, Sedan Cambrai merged with the Mount Torrens Football Club to form the Mount Torrens Cambrai Football Club.
 This merger would only last for ten years before the club split back into Sedan Cambrai and Mount Torrens in 1986.
 The reformed Sedan Cambrai entered the Mid Murray Football Association and played in that competition until it disbanded at the end of the 2009 season when they returned to the Hills Football League Country Division (Division 2).
 In 2015, Sedan Cambrai was voted out of the Hills Football League Division 2 competition by member clubs and were initially pushed into the C-Grade competition.
 They were reinstated for the 2015 season before shifting to the Riverland Independent Football League in 2016.
The Seattle Seahawks season was the franchise's 37th season in the National Football League and the third under head coach Pete Carroll.
 The Seahawks had a three quarterback competition with Tarvaris Jackson, Matt Flynn, and Russell Wilson.
 Jackson was traded to the Bills, and Wilson won the job.
The official 2014/2015 snooker world ranking points for the professional snooker players on the World Snooker Main Tour in the 2014/2015 season are based on performances in ranking and minor-ranking tournaments over a two-year rolling period.
 Following an overhaul of the world rankings it is the first season where the tariffs are based on prize money.
 Rather than being awarded points according to tariffs preset by the governing body as in previous seasons, the players are now ranked by their prize money earnings in tournaments that carry ranking status.
 The only exception to this is when a player loses their first match: for the 2012/2013 and 2013/2014 seasons only half the money earned for the event counts towards the player's ranking,<ref name="2013/2014 points schedule"> </ref> and for the 2014/2015 season a player will not receive any points at all for that tournament.
 Due to the transition to the new ranking system, the start ranks of the 2014/2015 season for the top 64 players are incongruent with the ranks of the players at the end of the previous season.
Baker Reagan Mayfield (born April 14, 1995) is a college American football quarterback for the Oklahoma Sooners.
 Mayfield began his college football career as a walk-on player for the Texas Tech Red Raiders.
 He is notable for being the first walk-on true freshman quarterback to start a season opener at a BCS school.
 Mayfield transferred from Texas Tech to Oklahoma following alleged scholarship issues and a lack of communication with coaches.
 After sitting out the 2014 season due to NCAA transfer rules, Mayfield won the starting quarterback job in 2015 over Cody Thomas and incumbent starter Trevor Knight.
Trevor Knight is an Australian musician.
 Together with Smoky Dawson he was nominated for a 1989 ARIA Award for Best Country Album for their single "High Country".
 The pair also won Golden Guitars in 1988 for "Days Of Old Khancoban" and 1989 for "High Country".
Trevor Knight (born October 3, 1993) is an American football quarterback for the Atlanta Falcons of the National Football League (NFL).
 He played college football for the Oklahoma Sooners and Texas A&M Aggies.
 After leading Oklahoma to an 8–5 record in the 2014 season, he lost the starting job in an open quarterback competition to Texas Tech transfer Baker Mayfield prior to the 2015 season.
 On January 4, 2016, it was announced that Knight would transfer to Texas A&M University.
Auto Da Fé were an Irish new wave musical group formed in the Netherlands in 1980 (but mainly active in Ireland) by former Steeleye Span singer Gay Woods and Trevor Knight.
 The band's sound incorporated keyboards and electronics.
 Woods stated "It was the happiest musical time I ever had so far.
 I learned so much.
 I was ridding myself of a lot of things that stifled me.
 It was so liberating for me to stand up and not be a "folky" anymore.
 It was the easiest thing in the world because I had yearned for so long to do that music.
 I still love the songs I wrote at the time".
The Safeway Open is a professional golf tournament, part of the PGA Tour.
 It was first staged in 2007 as the Fry's Electronics Open at Grayhawk Golf Club's Raptor Course in Scottsdale, Arizona.
 It was renamed to the Frys.com Open in 2008, and moved to California in 2010, at CordeValle Golf Club in San Martin.
 In October 2014, part of the PGA Tour's 2015 season, the tournament moved to the North course of Silverado Country Club in Napa.
 The purse was $5 million for the tournament's first seven years and was raised to $6 million for the 2015 season.
The 2015 Buffalo Bills season was the franchise’s 56th overall season as a football team, 46th in the National Football League, third under leadership of general manager Doug Whaley and first under new head coach Rex Ryan, who signed a five-year, $27.5 million contract on January 12, 2015 after having previously spent the past six seasons coaching the division-rival New York Jets, leading them to two straight AFC Championship games in 2009 and 2010, becoming the franchise’s 18th head coach and the fifth in the past seven years in the process.
 Ryan replaced Doug Marrone, who opted out of his contract on December 31, 2014 to take advantage of a contract loophole, fearing the Pegulas were going to fire him, hence the reason the Bills entered the 2015 season looking for a new head coach.
 Despite the bold prediction made by Ryan at his introductory press conference, where he stated, “I’m not going to let our fans down.
 I am not going to do that.
 I know it’s been 15 years since the Bills made the playoffs.
 Well, get ready, man, we’re going.
 We are going,” the Bills were unable to make the playoffs in their first season with Ryan as head coach, finishing with a record of 8-8 (the team’s first since 2002), making it the 16th straight season without a playoff appearance, which became the longest active in major professional sports after Major League Baseball’s Toronto Blue Jays broke their 22-year playoff drought on September 25, 2015.
 It was also the first full season under the ownership of Terry and Kim Pegula (whom also own the Buffalo Sabres), having purchased the Bills partway through 2014 after the death of longtime owner Ralph Wilson in March at the age of 95.
 The Bills began their season with an open competition for the starting quarterback position after Kyle Orton, the starter for most of the 2014 campaign, retired during the offseason, so the team acquired free agent Tyrod Taylor, a former backup quarterback of the Baltimore Ravens, who won the competition over incumbent second-string quarterback EJ Manuel and trade acquisition Matt Cassel, the latter of whom the team later traded along with a seventh-round pick in 2017 to the Dallas Cowboys, in exchange for a fifth-round draft pick in 2017.
