Associated Press - Robert Griffin III raised his fists, took a knee for a quick prayer, jumped up and pointed to the sky. That's the routine on touchdown passes for the Heisman Trophy winner from Baylor, and he got to do it four times in his impressive return to Texas.

Griffin III threw for 311 yards and Washington built a huge halftime lead against Dallas before holding on for a 38-31 victory that conjured memories for some of the rallies that helped make Cowboys vs. Redskins on Thanksgiving famous. Griffin made the Cowboys look like an overmatched college team in the second quarter, throwing for three scores in Washington's first 28-point quarter in 13 years as the Redskins (5-6) built a 28-3 halftime lead.

After Tony Romo threw the longest touchdown of his career -- an 85-yarder to Dez Bryant late in the third quarter -- Griffin answered by becoming the first Redskins quarterback with four touchdown passes in consecutive games.

And finally, when the Cowboys got within a touchdown and really had people thinking back to Clint Longley's miracle TD to Drew Pearson in the final seconds of a one-point Dallas victory over Washington on Thanksgiving in 1974, Griffin calmly led the Redskins on a clock-killing drive to a field goal and a 38-28 lead in his first pro game in Texas since his sparkling run at Baylor.

The Cowboys (5-6) actually contained Griffin in the first quarter, getting a sack and forcing an intentional grounding penalty that gave them good enough field position for an easy drive to a 3-0 lead.

Everything changed on Griffin's first big NFL play in Texas. He hit Aldrick Robinson in stride for a 68-yard touchdown and a 7-3 lead to spark the first 28-point quarter in 13 years for the Redskins (5-6).

Griffin's next big throw wasn't nearly as accurate, but Garcon somehow came down with it and outran the Dallas defense the final 45 yards on a 59-yard score for a 21-3 lead.

Romo's first interception in four games gave the Redskins a chance to get one more score before halftime when Hall returned it to the Dallas 33 with 30 seconds left. Out of timeouts at the Dallas 6 with 10 seconds left, the Redskins trusted Griffin to try to get a touchdown, and Moss kept both feet in while falling out of bounds for a 28-3 lead with 5 seconds left.

Griffin completed 12 straight passes from the middle of the first quarter to the middle of the third and finished 20 of 28. It was hard to tell with his final numbers, but the Cowboys did manage to put some pressure on Griffin. They sacked him four times, forced him to sprint out of the pocket a number of times and delivered hard hits after several throws.

The Dallas offense, playing most of the game without Miles Austin after he injured a hip early, never could answer in the decisive second quarter. The Cowboys had only two first downs while the Redskins were scoring four touchdowns. The Cowboys' best possession came right after Griffin's first big play, but Bryant fumbled in the open field at the end of what would have been a first-down catch. DeJon Gomes returned the fumble to the Dallas 49, and Alfred Morris scored from the 1 for a 14-3 lead. Morris had 113 yards on 24 carries.
