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 2003 Dallas Cowboys season was the 44th season for the team in the National Football League.
 Coming off three consecutive 5–11 seasons, Dallas hired former New York Giants, New York Jets, and New England Patriots coach Bill Parcells.
 In a scheduling coincidence, the Cowboys faced all three said teams in the 2003 regular season.
Jason Calvin Garrett (born March 28, 1966) is an American football head coach of the Dallas Cowboys of the National Football League (NFL).
 Garrett was the offensive coordinator and assistant head coach of the Cowboys before being promoted to interim head coach after the firing of Wade Phillips on November 8, 2010.
 He is a former professional American football quarterback in the National Football League for the Dallas Cowboys, New York Giants, Tampa Bay Buccaneers and Miami Dolphins.
 He played college football at Princeton University.
Charles Wade Wilson (born February 1, 1959) is an American football coach and former quarterback who played for the Minnesota Vikings, Atlanta Falcons, New Orleans Saints, Dallas Cowboys and the Oakland Raiders in a seventeen-year career from 1981 to 1998 in the National Football League (NFL).
 He is currently the quarterbacks coach for the Dallas Cowboys, a position he has held since 2007.
 He played college football for Texas A&M University-Commerce (formerly East Texas State), where he was an NAIA All-American Quarterback and led the Lions to the NAIA national semifinals during the 1980 season.
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.
Duane Charles "Bill" Parcells (born August 22, 1941), also known as The Big Tuna, is a former American football coach, best known as a head coach in the National Football League (NFL) for 19 seasons.
 He rose to prominence as the head coach of the New York Giants, whom he led to two Super Bowl titles.
 Parcells later served as the head coach of the New England Patriots, New York Jets, and Dallas Cowboys.
 Throughout his career, he coached teams that were in a period of decline and turned them into postseason contenders.
 He is the only coach in NFL history to lead four different teams to the playoffs and three different teams to a conference championship game.
Kenneth Don Gray (born March 10, 1936 in San Saba, Texas) was an offensive guard who played 13 seasons in the National Football League for the Chicago Cardinals/St. Louis Cardinals and the Houston Oilers.
 Gray attended and played football for four seasons at Howard Payne University.
 His first NFL contract, in 1958, paid him $6,000.00.
 In those days the league was composed of 12 teams, split into two divisions.
 After retiring as a player, earning six All-Pro awards, he served for three years as head coach at his high school alma mater, Llano High and offensive line coach for the 1977 AFC Champion Denver Bronco team that earned its way to Super Bowl XII, to play against the Dallas Cowboys.
 In 2016, he was inducted into the Texas Sports Hall of Fame along with former University of Texas head football coach Fred Akers, former Dallas Cowboys offensive lineman Larry Allen and former Major League Baseball pitcher Andy Pettitte.
 He earned a spot on the St. Louis Cardinals’ All-Time Team and the NFL All-1960s Team.
 A Christian, Gray first and foremost considers himself blessed with his lovely and gracious wife, Shirley, who has stood by him through all the years of risking injury in high school, college and league play, and the unique challenges of his coaching years to the present.
 They met and were wed back in their high school days at Llano High School.
 Their union produced two fine sons, Shane and Boyd and a grand child, Garret.
The New England Patriots season was the franchise's 44th season in the National Football League and the 54th overall.
 The Patriots finished 12–4 and with the AFC's No. 2 seed for a second consecutive season.
 Along with their seeding, New England was awarded a first-round bye in the playoffs for the fourth season in a row, only the second such occurrence for any team since the league switched to a 6-team playoff format in 1990 (the others being the 1992-95 Dallas Cowboys).
 The Patriots defeated the Indianapolis Colts 43–22 in the Divisional round of the playoffs, but lost in the AFC Championship game to the Denver Broncos, by a score of 26–16.
The 1993 Cleveland Browns season was the team's 44th season with the National Football League.
 This season was notable for coach Bill Belichick deciding to bench, and then ultimately release, longtime starting quarterback Bernie Kosar in favor of Vinny Testaverde.
 Kosar resurfaced during the season with the Dallas Cowboys, when he was part of the eventual Super Bowl champions as a fill-in for injured quarterback Troy Aikman.
 The Browns get off to a 5-2 start despite the Quarterback Controversy.
 Prior to the start of the season the Browns signed Free Agent Quarterback Vinny Testaverde.
 Originally Testaverde was supposed to back-up his former University of Miami teammate Bernie Kosar.
 However, when Testaverde performed better when given the opportunity to play some felt there should be a change at the Quarterback position.
 However, the Browns went beyond that by unceremoniously releasing Kosar in the middle of the season.
 The Browns lost their next four games and seven of their last nine games to finish with a 7-9 record.
The 1968 New York Giants season was the 44th season for the club in the National Football League.
 For the 1968 season, the Giants traded divisions with the New Orleans Saints, with the Giants moving from the Century Division to the Capitol Division.
 The Giants finished with a 7–7 record, which placed them second in the Capitol Division, five games behind the Dallas Cowboys.
