ARLINGTON, Texas (AP) -- Robert Griffin III will always be RG3. That didn't stop Washington coach Mike Shanahan from trying something a little different after his rookie quarterback was equal parts sparkling and steady in his Texas debut.
"He's kind of like 'Cool Hand Luke,'" Shanahan said. "He doesn't get too upset about anything."
The Heisman Trophy winner from Baylor threw for three touchdowns in a dazzling second quarter, then calmly quelled a Dallas rally reminiscent of a comeback that made Cowboys vs. Redskins on Thanksgiving famous, leading Washington to a 38-31 victory Thursday.
Griffin told anyone who asked he didn't think his first pro game in his home state on Thanksgiving would overwhelm him. He wasn't kidding.
"I knew I had that feeling that I was back home where I had spent so many years, but it didn't drive me through the roof emotionally as far as getting charged up for the game," said Griffin, who grew up a Denver Broncos fan in Central Texas. "It was a normal game, even though it was a Thanksgiving Day game."
Griffin finished with 311 passing yards and four TDs, and made Dallas look like an overmatched college team in building a 28-3 halftime lead thanks to a 28-point second quarter, the first for the Redskins (5-6) in 13 years.
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 TD tosses in consecutive games.
When the Cowboys (5-6) 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 for a 38-28 lead.
"Really, I have to almost pinch myself to realize that he was out there playing against Texas Tech about a year ago, and here he is really doing a number on us," Cowboys owner Jerry Jones said in referring to a Baylor win at Cowboys Stadium in which Griffin played just half the game because of concussion-like symptoms. "I was in awe of RG3, and the plays that he was making."
Romo lost for the first time in six starts on Thanksgiving, despite a career-high 441 yards and three second-half touchdowns. After the long TD to Bryant, who matched his career high from last week with 145 yards receiving, Romo threw a TD to Felix Jones, ran in the 2-point conversion and threw another scoring pass to Bryant to help Dallas close to 35-28 with 8:24 remaining.
"I thought we had a good chance," said Romo, who tied a career high with 62 pass attempts.
Griffin, who threw just his fourth interception the previous possession, responded by completing three passes for first downs -- including a third-and-1 near midfield -- and the Redskins ran nearly 5
