The team's greatest current rival was their first historic rival. They defeated the Cowboys for the NFL championship in back to back years in the late 60's. In both contests the Cowboys lost on the last play. To make matters worse, the winner played in the first two ever Super Bowls, before the merger. The Cowboys were just a few plays away from the SB trophy being called "The Landry".
The Cowboys greatest rival is the team that destroyed a desperate Cowboy team halfway through the 2010 season, resulting in Jerry Jones firing Wade Phllips. To make it even worse, the Super Bowl was in Dallas that year amd guess who came to town as the NFC champs. To add insult to injury, a Broadway play about their iconic head coach of the sixties debuted. The backdrop was those championship games. Imagine a Broadway play in which Tom Landry ia the bad guy!
It is the same team that recieved two more miracles, responsible for the Cowboys last two playoff defeats. Seemingly magical seasons ended on a catch that should have been and a catch that, 9 out of 10 times, would never have been.
The Commanders are a pest, the Giants are a temporary annoyance, the Steelers are declining, the 49ers are a joke, the Eagles wamt to be the Cowboys.....
.......But the Packers want historical relevance, nobody cares about the championships they won when there were 3 teams in the league so they want to take championahips away from the Cowboys.
