From my perspective, it's the Commanders. The Commanders have stopped us from going to the Super Bowl twice.
And they always seem to trip us up or beat us when they're not expected to. Who can forget the Santana Moss comeback or the fluky defeat during our 13-3 year or the loss with Colt McCoy that may have stopped us from securing home-field advantage throughout the playoffs in 2014? And, remember, we kept the Commanders from an undefeated season in 1991.
For the most part, the Eagles rivalry really started with Buddy Ryan. Yes, they stopped us from going to a Super Bowl also, but they haven't really beaten us in meaningful games or when they've beaten us it's because we really sucked as a team.
Philly beat us in an NFC championship game during the Landry / Staubach years. Never forget the " injured" Wilbert Montgomery ripping off a long TD run against us early in the game that set the tone for the loss.
- NFC Championship Game, January 11, 1981 - After losing to the Cowboys in all but 3 games from 1967–79, the Eagles finished first in the NFC East in 1980 due to tie-breaking procedures (both teams 12–4 and splitting the meetings between each other, but the Eagles having scored more points) and thus claimed the number one overall seed. The 1980 NFC Championship was also called the "Blue Jersey Game", on the account that the Eagles, having the choice as the home team, made the Cowboys wear their seemingly cursed blue jerseys (a stigma that dated back to Super Bowl V). To the cheers of a roaring Veterans Stadium crowd, the Eagles defeated the Cowboys 20-7.
Eagles went to SB that year losing to Oakland Raiders 27-10 Plunkett vs Jaworski - enjoyed watching Jaws get picked by a linebacker 3 times....... he conveniently forgets these when he talks about Romo getting picked by a LB when he does his QB sessions on TV.....
Super Bowl XV
Tom Flores'
Oakland Raiders beat Dick Vermeil's
Philadelphia Eagles,
27-10, in Super Bowl 15 on January 25th, 1981 at the
Louisiana Superdome in New Orleans.
Ron Jaworski had 291 yards, but was intercepted by linebacker Rod Martin three times. Jim Plunkett threw three touchdowns in Super Bowl Fifteen; an
80 yard bomb to Kenny King, and two shorter scores to
Cliff Branch. An Eagle defense led by John Bunting and Herman Edwards couldn't slow Plunkett and Mark Van Eeghen (75 yards). Ted Hendricks, Matt Millen, Dave Browning, and Martin led the stout
Raider defense.
