The NFC East sent three of its four teams to the playoffs last season and all of them won at least one postseason game in the process. Needless to say, the group did very well.
Even when the division performs poorly, it is usually at the front and center of the NFL given the markets the teams occupy. Generally speaking, the Dallas Cowboys, Philadelphia Eagles, New York Giants and (to a lesser degree) Washington Commanders always draw a crowd so when they are playing well things are all the more elevated.
