When the Seahawks couldn’t reach the goal line at the end of Sunday night’s NFC West title matchup with San Francisco, they inadvertently allowed the Eagles to reach a goal of their own.

Seattle, the Eagles’ opponent in Sunday’s NFC wild-card game at Lincoln Financial Field, was the only one of their 15 NFC rivals the Eagles had never played in the postseason.

The Eagles’ postseason history began on Dec. 21, 1947, when they shut out the Steelers, 21-0, and runs through the Jan. 13, 2019, loss to the Saints. In that span, they faced every current conference opponent except Seattle.

Philadelphia met seven of them four times each (Bears, Giants, Falcons, Saints, Buccaneers, Vikings and Cowboys), three others on three occasions (Cardinals, Rams and Packers) and four teams just once (Redskins, Lions, 49ers and Panthers).
