The Philadelphia Eagles season was the franchise's fifty-ninth season in the National Football League.
Despite having a 10–6 record and finishing with the top-ranked defense in the NFL, the Eagles failed to make the playoffs. During Week 1, quarterback Randall Cunningham was lost for the season with a knee injury.
Background
Statistics site Football Outsiders ranks the 1991 Eagles, coordinated by Bud Carson, as the greatest defensive team in its ranking's history. According to Football Outsiders: The 1991 Eagles completely lap the field in terms of defensive DVOA. Only the 2002 Bucs had a better pass defense, and only the 2000 Ravens had a better run defense, and the Eagles were much more balanced than either of those teams.
It's crazy to imagine how few points the Eagles might have given up if they were playing with a halfway-decent offense instead of losing Randall Cunningham to a torn ACL in the first game of the season. The Eagles were stuck depending on an over-the-hill Jim McMahon for 11 starts, plus Jeff Kemp for two and Brad Goebel for two. McMahon actually wasn't half bad ... but the other two quarterbacks were awful, especially Goebel who had no touchdowns with six interceptions. And the running game was dreadful, with 3.1 yards per carry as a team.
Still, the Eagles were fifth in the league in points allowed, and first in yards allowed by nearly 400 yards – and the team that was second in yards allowed is also on that top-ten defenses list, the 1991 New Orleans Saints. The Eagles allowed 3.9 yards per play, where no other team allowed fewer than 4.5. As bad as their running game was, their run defense was even better, allowing 3.0 yards per carry. Three-fourths of the starting defensive line was All-Pro (Reggie White, Jerome Brown, and Clyde Simmons). Linebacker Seth Joyner and cornerback Eric Allen made the Pro Bowl as well.
Overview
A "real" fresh start
On January 8, team owner Norman Braman opted not to renew the contract of Buddy Ryan, the Eagles' head coach since 1986. On the same day, Braman promoted then-offensive coordinator Rich Kotite, making him the eighteenth head coach in the club's history. The team opened with a 3–1 mark, its best start since 1981, despite having lost Cunningham for the year due to a knee injury that was sustained in Green Bay thanks during an opening day-hit by Bryce Paup. After taking over and leading the Eagles to a solid start, backup QB Jim McMahon was also injured in Game 5 during a shutout loss to the Redskins.
A winless October
With McMahon sidelined, the Birds offense stalled completely during a stretch of eleven straight quarters without scoring a touchdown that culminated in a four-game skid. By mid-season, Philadelphia had used five different quarterbacks, including rookie Brad Goebel, former Jets backup Pat Ryan and former Niners third-stringer Jeff Kemp in eight games and saw its record sink to 3–5. Bleeding Green Nation ranked it as one of the worst Eagles backup QB seasons in the team's history, illustrating how the defense would have supported better quarterback play to several victories.
A relatively healthy McMahon returns
Week ten saw McMahon return to the lineup for a Monday night, 30–7 victory over the defending Super Bowl Champion New York Giants at Veterans Stadium; however, the following week at Municipal Stadium proved to be a tighter-scoring game. The Eagles won 32–30 as Philadelphia spotted Cleveland a 23–0 lead early in the second quarter, before staging a comeback behind a battered McMahon (passing for 341 yards and three touchdowns). Before the game, McMahon's elbow was so swollen, his roommate Ron Heller had to tie his ponytail for him, and then told his lineman he wouldn't be able to play. But Birds trainer Otho Davis used a concoction he calls "Grandma's Goop" on the elbow, enabling McMahon to play.
These wins resurrected the season, and the Birds continued to surge into contention for a playoff berth with a six-game winning streak (the club's longest since the start of '81). This upped the team's record to 9–5.
The signature win of the run was a 13–6 Monday night victory against the Oilers in Houston on December 2, later dubbed the "House of Pain" game for the Eagles' defense-punishing Warren Moon and his teammates.
Heart of a champion
