Question: Which American football player who played 15 seasons for the Dallas Cowboys and retired in 1989 was a big factor in the 1983 Dallas Cowboys season?
Context: 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. Ed Lee "Too Tall" Jones (born February 23, 1951) is a retired American football player who played 15 seasons (1974–1978, 1980–1989) in the National Football League (NFL) for the Dallas Cowboys.  In 1979, he briefly left football to attempt a career in professional boxing. Vashone LaRay Adams (born September 12, 1973) is a retired American professional football player who played five seasons in the National Football League with the Cleveland Browns, Baltimore Ravens New Orleans Saints, Kansas City Chiefs and Dallas Cowboys.  Adams first attended Fort Hays State University and Butte Junior College before transferring to Eastern Michigan University.  After college, Adams was signed as an undrafted free agent by the Cleveland Browns.  In his rookie season of 1995, Adams played in 8 games, started 6 of them and recorded 23 tackles.  The following season, the Cleveland Browns moved to Baltimore and became the Baltimore Ravens.  While with the Ravens, Adams recorded the only interception of his career, returning it for 15 yards.  Adams joined the New Orleans Saints for the final season of his career, playing in 5 games, earning 4 starts and recording his only forced fumble.  He would later sign contracts with the Kansas City Chiefs in 1998 and Dallas Cowboys in 1999. The 2010 Dallas Cowboys season was the 51st season for the team in the National Football League, and the second season playing their home games at Cowboys Stadium.  After falling to the Minnesota Vikings in the divisional round of the 2009-10 NFL Playoffs, the Cowboys sought to defend their NFC East division title and contend for a Super Bowl Championship, particularly given that Super Bowl XLV would be played at Cowboys Stadium.  However, this did not happen and after a 1–7 start Wade Phillips became the first coach in Cowboys history to be fired during the season.  He was replaced by offensive coordinator Jason Garrett.  The Cowboys finished the season 6–10, 3rd place in the NFC East, and failed to reach the playoffs.  However, under Garrett the team's record was 5–3 as compared to the 1–7 start under Phillips. Charles Louis "Chuck" Howley (born June 28, 1936) is a former American football linebacker who played in the National Football League (NFL) for 15 seasons, primarily with the Dallas Cowboys.  Howley was a member of the Chicago Bears in his first two seasons and spent the remainder of his career with the Cowboys.  He was named the MVP of Super Bowl V and is the only player on a losing team to receive the award. Gerald J. Tubbs (January 23, 1935 – June 13, 2012) was an American football linebacker who played for ten seasons in the National Football League from 1957 to 1966, mainly for the Dallas Cowboys.  He was selected by the Dallas Cowboys in the 1960 NFL Expansion Draft.  After his retirement he stayed with the Cowboys as an assistant coach for 22 years.  He played college football at the University of Oklahoma.  In 1996, he was inducted into the College Football Hall of Fame. The 2002 Dallas Cowboys season was the 43rd season for the team in the National Football League.  It was Emmitt Smith's 13th and final season with the team, officially marking the end of the famed "triplets" tenure in Dallas after wide receiver Michael Irvin was forced to retire prematurely after the 1999 season and quarterback Troy Aikman retired prior to the start of the 2001 season.  All three players would eventually be inducted to the Pro Football Hall of Fame.  It was also the last of three consecutive 5-11 finishes for the Cowboys, beginning in 2000. The 2009 Dallas Cowboys season was the 50th anniversary for the team in the National Football League.  It was the team's first season playing at Cowboys Stadium.  Their victory over the Oakland Raiders on November 26 extended their Thanksgiving winning streak to four in a row and also ended a three-game losing streak to the Raiders.  They also ended the Saints' bid for a perfect season after a 13–0 start with a 24–17 victory on December 19, 2009.  The Cowboys punched their ticket to the playoffs on December 27 after beating the Washington Redskins 17–0.  On January 3, 2010, the Cowboys clinched their division with a win over the Philadelphia Eagles, 24–0.  In the wild-card round of the playoffs, the Cowboys once again defeated the Eagles, 34–14, to score their first playoff win since 1996 and finish the season sweep of all three games played against Philadelphia.  They lost 34-3 to the Minnesota Vikings in the divisional round of the playoffs, effectively ending their season. 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 Dallas Cowboys completed the 1983 season with a record of 12 wins and four losses, finishing second in the NFC East.  The team started the season with seven straight victories, including a memorable Monday night win over the Washington Redskins in which the team erased a 20-point halftime deficit and prevailed, 31–30.  The Cowboys were particularly strong on offense, led by quarterback Danny White and running back Tony Dorsett.  The Cowboys scored a team record 479 points and staged a few come-from-behind victories during the season.  However, the defense gave up many points, despite strong play from Randy White, Ed "Too Tall" Jones, and Everson Walls.  In particular, the young secondary was guilty of giving up many big plays throughout the season.
Answer: Ed "Too Tall" Jones
