For the 2014 season, the Eagles officially adopted the "Elite 51″ style uniform from Nike. However, they only broke out the midnight green jerseys and pants in the second half of that season due to the difficulty of producing their preferred shade of midnight green. Recently the team has discussed bringing back the "Kelly Green" uniforms similar to the uniforms worn in the 1960 NFL Championship season, which were last worn in the 2010 season opener vs. Green Bay. Traditionally, kelly green, silver and white had been the official team colors, until the 1996 season when it changed to the current "Midnight Green" uniforms. NFL rules and restrictions require that teams go through a waiting period before any major uniform changes and alterations can be made, which means it would likely be quite some time before any uniform changes are officially made. In Week 6 of 2014 against the New York Giants, the team introduced black pants to complement their black jerseys, giving them a blackout uniform set. The Eagles won the game 27–0. The victory was their first shutout in 18 years. In Week 16 of 2016 (also against the Giants), the Eagles wore a variation of the all-black look as part of the NFL Color Rush program, but with solid black socks as opposed to black with white sanitary socks of the original look. The black jerseys/white pants combination was last seen during a preseason road game against the New England Patriots, after which the black jerseys were paired exclusively with the black pants. In 2018, the Eagles' midnight green pants were not worn at all, marking the first such instance since the 1996 rebrand that the Eagles wore only white pants with their primary white or midnight green jerseys. In Week 6 of the 2017 season, the Eagles debuted an all-white look with white jerseys, white pants and solid white socks in a road game against the Carolina Panthers. The all-white look began to be utilized full-time as a road uniform set in 2019 thanks to the NFL's decision to allow teams to wear solid color socks as an alternate look. The Cowboys have been one of the Eagles' biggest rivals. The Eagles won the first game in this rivalry 27–25 on September 30, 1960. Dallas leads the all-time series 63–51. They have been close in recent years, with both teams winning 12 games since 2006. There is a lot of hostility between the two teams' fan bases, with incidents such as the 1989 Bounty Bowl. The rivalry has even spilled over into Draft Weekend, with Cowboys legend Drew Pearson and Eagles legend David Akers exchanging insults at the opposing franchise in 2017 and 2018, respectively.
