What it means: Eagles coach Chip Kelly officially has a bad loss on his NFL résumé. His Eagles were in first place in the NFC East, facing a 3-9-1 team without its best player, running back Adrian Peterson. Instead of securing their hold on a playoff berth, the Eagles were flat and looked unprepared and poorly coached in all three phases. Kelly didn’t use running back LeSean McCoy enough and handed the Vikings three points by going for a fourth-and-1 at his own 24-yard line in the third quarter. Defensive coordinator Bill Davis had no answers for Matt Cassel, even with the Vikings down to a practice-squad running back. Special-teams coach Dave Fipp’s plan to kick away from Cordarrelle Patterson gave the Vikings great field position all game.
Shredded and wounded: Philadelphia's secondary was terrible even before losing nickel corner Brandon Boykin (possible concussion) and safety Kurt Coleman (hamstring). Cassel beat the Eagles deep for a 57-yard touchdown to Greg Jennings in the first quarter. He was able to convert third downs all too easily. Safety Patrick Chung was benched in favor of Coleman, then had to return when Coleman got hurt. Colt Anderson, forced into action, got burned on a big play by tight end Chase Ford. To make matters worse, the secondary committed a rash of penalties in the fourth quarter to fuel a Vikings touchdown drive.
Stock watch: Falling: Nick Foles. He wasn’t Sports Illustrated-cover-jinx terrible, but the magic carpet ride is over. Foles took sacks by holding the ball too long. He threw a jump ball for DeSean Jackson that was intercepted. Foles was also called for a penalty for an illegal block, which negated a Jackson touchdown run on a reverse. Foles threw three second-half touchdown passes, but his chance to stage a comeback win was undermined by the Eagles’ inability to stop the Vikings at all.
What’s next: The Eagles face two must-win games. They host the Chicago Bears next week in a game that was flexed into prime time. Then they finish the regular season at the Dallas Cowboys, a game that could decide the NFC East title. The Eagles, who would lose on tiebreakers if they finish with the same record as the Cowboys, made things harder on themselves by not taking care of the Vikings.
