With 1:36 left in the first half Sunday, Redskins quarterback Robert Griffin III committed his one blemish for the day. He threw an incomplete pass. And then his day continued. And he went back to being, well, perfect.

Thanks in part to Griffin -- but with a large assist from the defense -- the Redskins snapped a three-game losing streak in a 31-6 win over Philadelphia. The Redskins improved to 4-6 heading into Thursday's game at Dallas. The Eagles (3-7) have lost six straight.

Griffin made sure the Eagles continued those losing ways by completing 14 of 15 passes for 200 yards and four touchdowns. He added another 84 yards on 12 runs.

"Except for that one incompletion, I thought he did OK," Redskins coach Mike Shanahan said.

Yes, he was kidding. No, there was no need for clarification after that joke.

While the playoffs remain a long shot, the Redskins left themselves in the conversation for another four days at least. The defense deserves credit for holding Philadelphia to 257 total yards and for forcing three turnovers, which led to 10 points.

Meanwhile, Griffin's completion percentage of 93.3 was the second best in a game in the NFL this season, trailing only San Francisco's Alex Smith (94.7 percent against the Cardinals in October).

"Robert is going to go out there and be special," said Redskins receiver Santana Moss, who was on the receiving end of a 61-yard touchdown pass. "He really ignites our fire. When he is doing his thing, he's on fire, and then it just rubs off on everyone else. I'm glad to have a guy like that."

As usual, Griffin made plays with his arm and his legs -- and received help from teammates and coaches.

On a third-and-6 from the Washington 24-yard line in the second quarter, Griffin dropped back against a four-man rush. He looked right and back to the middle, then escaped the pocket to the left. Linebacker Mychal Kendricks underestimated Griffin's speed, taking too shallow an angle, and Griffin turned the corner for a 10-yard gain.

Here's why that play mattered: Three plays later, Griffin hit receiver Aldrick Robinson for a 49-yard touchdown pass and 14-3 lead. Griffin, who also had touchdown passes of 6 yards to fullback Darrel Young and 17 yards to tight end Logan Paulsen, did nothing special on this play. Rather, the scheme helped as tight end Niles Paul was open over the middle, drawing attention from safety Nate Allen and leaving the middle wide open.

"He said all week he wanted to dominate, and that's what he did," Robinson said of Griffin.

Another scramble resulted in another frustrating series for the Eagles. The Redskins, leading 17-6 but sputtering, faced third-and-14 from their own 16 in the third quarter. Griffin turned good coverage by the Eagles into a frustrating play for their defense when he scrambled around the end for 23 yards.

That scramble mattered because of what followed three plays later. This time, Griffin unloaded a deep ball to Santana Moss, double covered inside the 5-yard line. A potential mistake turned into a touchdown when Moss outjumped safety Kurt Coleman for the ball and then slipped free of cornerback Brandon Boykin's tackle attempt for a 61-yard score.

"It was an 'Oh, no, oh, yes,'?" Shan?ahan said. "Santana made a great play, and Robert gave him a chance."

That's what he did for the rest of his team as well.
