The 2008 Dallas Cowboys season was the 49th season for the team in the National Football League.
 The season ended when the Cowboys were blown out by the Philadelphia Eagles 44–6 in week 17, their worst loss since the 1985 Chicago Bears came to Texas Stadium and beat the Cowboys 44–0.
 It was the last season the Cowboys played at Texas Stadium; they moved to Cowboys Stadium in 2009.
 Despite entering the last month of the season four games above .500, they failed to make the playoffs, losing three of their last four games and finishing with a 9–7 record.
Dallas Cowboys Cheerleaders: Making the Team is an American reality television series that premiered in 2006 on Country Music Television.
 The series follows the auditioning process and the making of the annual Dallas Cowboys Cheerleaders squad.
 The series features DCC director Kelli McGonagill Finglass and choreographer Judy Trammell (both of whom are former DCCs from the 1980s), and former Army drill sergeant Jay Johnson (who is the founder of "Boot Camp Fitness" and is responsible for the conditioning drills each girl must perform for testing).
 Hundreds of young women audition each year and are put through the DCC "training camp" system before being cut down to the final 36 squad members for the first home football game of the Dallas Cowboys' preseason.
The Dallas Cowboys Radio Network is an American radio network broadcasting all Dallas Cowboys football games to stations across all of Texas, Arkansas, Oklahoma, Louisiana, and New Mexico during the NFL season.
 Beginning with the 2009 NFL season, it is the arm of CBS Radio and comprises over 50 stations with KRLD-FM in Dallas being the flagship station.
 Beginning in the 2011 NFL season, a separate contract will allow the network to be carried nationwide through Compass Media Networks.
The 2000 Dallas Cowboys season was the 41st season for the team in the National Football League.
 Cowboys owner Jerry Jones would promote the team's long-time defensive coordinator, Dave Campo, to be the fifth head coach of the Dallas Cowboys.
 This was also Troy Aikman's last season with the team.
The 1998 Dallas Cowboys season was the Cowboys' 39th season in the NFL.
 Team owner Jerry Jones would hire former Pittsburgh Steelers offensive coordinator Chan Gailey to be the fourth head coach of the Dallas Cowboys franchise.
Jerral Wayne Jones Sr. (born October 13, 1942) is an American businessman, best known for being the owner, president, and general manager of the Dallas Cowboys National Football League (NFL) team.
The Dallas Cowboys are a professional American football team based in the Dallas–Fort Worth metroplex.
 The Cowboys compete in the National Football League (NFL) as a member club of the league's National Football Conference (NFC) East division.
 The team is headquartered in Frisco, Texas, and plays its home games at AT&T Stadium in Arlington, Texas, which opened for the 2009 season.
 The stadium took its current name prior to the 2013 season.
 The Cowboys joined the NFL as an expansion team in .
 The team's national following might best be represented by its NFL record of consecutive sell-outs.
 The Cowboys' streak of 190 consecutive sold-out regular and post-season games (home and away) began in 2002.
 The franchise has made it to the Super Bowl eight times, tied with the Pittsburgh Steelers, and the Denver Broncos for second most Super Bowl appearances in history, just behind the New England Patriots record nine Super Bowl appearances.
 This has also corresponded to eight NFC championships, most in the NFC.
 The Cowboys have won five of those Super Bowl appearances, tying them with their NFC rivals, the San Francisco 49ers, and the AFC's Patriots; all three are second to Pittsburgh's record six Super Bowl championships.
 The Cowboys are the only NFL team to record 20 straight winning seasons (1966–85), in which they only missed the playoffs twice (1974 and 1984), an NFL record that remains unchallenged.
The 2017 Dallas Cowboys season is the franchise's 58th season in the National Football League, the ninth playing their home games at AT&T Stadium and the seventh full season under head coach Jason Garrett.
 It is also the 29th season under current owner Jerry Jones, meaning that by the end of the season his tenure as owner will equal the combined tenures of previous owners Clint Murchison, Jr. and H.R. "Bum" Bright.
William Russell "Fritz" Hawn (January 13, 1910 – December 8, 1995) was an American businessman and philanthropist who bred and raced Thoroughbred horses, served for twenty years as president of Del Mar Racetrack, owned by lifelong friend Clint Murchinson with whom he became a founding partner in the Dallas Cowboys franchise of the National Football League.
 He sold his interest in the Dallas Cowboys in 1984.
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.
