EAST RUTHERFORD, N.J. -- If the New York Giants miss the playoffs once again, they have only themselves and the Washington Redskins to blame.

Rex Grossman threw a touchdown pass and the Redskins put a major hurt on the Giants and their playoff hopes with a dominating 23-10 victory Sunday in a game in which New York showed little desire with much on the line.

"I'm very disappointed in how we played today," coach Tom Coughlin said after the Giants (7-7) fell a game behind Dallas (8-6) in the NFC East with two games left in the regular season.

"I accept responsibility for it. But I expected to see more -- quality execution -- and we didn't get that."

Surprisingly, Washington (5-9) looked very much like a playoff team in winning for only the second time in 10 games and embarrassing the Giants for the second time this season.

Grossman and the offense held the ball for 35 minutes, while the defense picked off Eli Manning three times and didn't allow a touchdown until the final minute.

"They had a lot at stake and obviously we didn't and I'm pleased the way we played," Redskins coach Mike Shanahan said.

Coming off an emotional win over Dallas on Sunday night in a game that gave them control of their own destiny, the Giants showed nothing after a couple of early interceptions.

"I didn't see the passion in us today," running back Brandon Jacobs said. "We didn't play well. We disappointed each other and our fans, and we've just got to play better. I can't tell you why."
