Context paragraphs:
Dallas Cowboys: 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.

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.
