1 McCoy is back » Star running back LeSean McCoy was injured late in the game vs. Redskins on Nov. 18 -- a devastating 31-6 loss. He will return from a concussion and start for the first time since that game but is unlikely to get his full workload, according to Eagles coach Andy Reid. McCoy was held to 45 yards on 15 carries in that first game. But he is a dual-threat, after all, and did rip off 67 receiving yards thanks to multiple screen plays that the Redskins struggled to adjust to in the first half of that contest.

2 Foles, Take 2 » Nick Foles will try to do better the second time around. Philadelphia's quarterback made his first career start during that Nov. 18 game at FedEx Field and had his moments. He completed 21 passes for 204 yards. But the Redskins also confused the rookie with coverages and took advantage of a struggling Eagles offensive line. Foles was sacked four times and threw two interceptions. His best game by far was two weeks ago against Tampa Bay with 381 passing yards and two touchdowns.

3 Not so special » Special teams has been pretty good for the Redskins all season. For Philadelphia? Not so much. The Eagles have allowed 522 punt return yards, the most in the NFL, with a touchdown against. And they're pretty mediocre on kickoff coverage, too, with 927 yards allowed. That ranks 15th overall. That's an area in which Washington can take advantage of a significant weakness. One positive: Kicker Alex Henery has made 25 of 28 kicks, including 11 from beyond 40 yards.

4 Defensive woes » The Eagles have been a disaster on defense all season and fired their coordinator, Juan Castillo, in October. The results really haven't improved much at all since then, and the Eagles have allowed 26.8 points per game overall. But the defensive line has a pair of nice prospects in Brandon Graham, a defensive end, and Fletcher Cox, a tackle. Both are recent first-round picks, and both will anchor the rebuild that's already underway. They each have 5? sacks to lead Philadelphia, though neither began the year as a starter. Washington's offensive line, dealing with injuries of its own, will have to account for that duo. Robert Griffin III tossed four touchdown passes in that first meeting against a demoralized Eagles secondary.
