The New Orleans Saints were an original member along with the Cowboys, Eagles, and Redskins when the East was formed as the Capitol division in 1967. The Saints were replaced by the Giants after one year, only to come back the next year just to be replaced by the Giants for good in 1970. The St. Louis and then Arizona Cardinals were members of the division from the AFL/NFL merger up until realignment in 2002.
The NFC East leads the NFL in total Super Bowl championships and NFC titles with 21 and 13 respectively. All four of the member teams have won a Super Bowl ring.
Dalla has the most appearances at eight and the most Lombardi Trophies with 5. New York comes in second with four and Washington has tallied three Super Bowl victories. Philadelphia only has one but they are the most recent champions, winning in 2017.
The massive amounts of success have also led to the division being the most valuable in football, with all four teams ranked in the top 10 for overall franchise value.
