PHILADELPHIA -- LeSean McCoy spotted Howard Mudd standing on crutches on the sideline and slowed up to give the 69-year-old assistant coach a pregame chest bump.
No one else could stop McCoy.
"I feel like every game is a chance for me to prove myself," McCoy said. "At any given time, any one of our guys could go off."
Mudd, the team's offensive-line coach, was on crutches because he had hip surgery during the bye week.
The time off helped him and the Eagles (3-4).
They dominated right from the start, improved to 13-0 after a bye under coach Andy Reid and snapped a five-game losing streak at Lincoln Financial Field that dated to last season.
"We started fast," Vick said. "That was our mindset. We wanted to set the tempo. We didn't want to let up."
Dallas defensive coordinator Rob Ryan fired up the Eagles with some trash-talking during the summer after they added several big-name players.
Ryan, the son of beloved former Philadelphia coach Buddy Ryan, called the Eagles the "all-hype" team and predicted the Cowboys would "beat their (butt)."
He was way off.
The Eagles racked up 495 total yards and held the ball for 42:09. They thoroughly outplayed a defense that came in ranked seventh in the NFL.
The long-haired Ryan paced the sideline and desperately tried to figure out how to stop Vick and Co. It didn't happen until the fourth quarter when the game was out of reach.
"I got outcoached by Reid and their staff," Ryan said. "It's ridiculous. I never gave our guys a chance. The whole thing was on me."
DeMarcus Ware was one of the few players who played well for Dallas (3-4). He had four sacks, and has 12 this season.
Coming off a 253-yard rushing performance in a win over St. Louis, Cowboys rookie DeMarco Murray was held to 74 yards on only eight carries.
"We weren't up to the task tonight," Cowboys coach Jason Garrett said. "This game is not coming back. We can learn from it and move on to the next challenge. We didn't execute in any phase of the football game."
The defending NFC East champion Eagles entered the season with a Super Bowl-or-bust mentality after adding six former Pro Bowl players in free agency and trades.
But a 1-4 start had people wondering if the self-proclaimed "Dream Team" -- backup quarterback Vince Young gave the Eagles that label after signing a one-year deal -- was overhyped as Ryan boldly declared in August.
After two straight wins, the Eagles are in a three-way tie with Dallas and Washington for second place behind the New York Giants (5-2).
"They've been very willing to work," Reid said. "It's important you have the right attitude to correct mistakes. We'll continue to do that. We've got plenty of room to improve."
Vick completed 21 of 28 passes for 279 yards and led the Eagles to points on their first six possessions. He also ran for 50 yards.
McCoy had 80 of Philadelphia's 115 yards rushing in the first quarter. That was more than Dallas allowed in any game this season. The Eagles entered with the No. 1-ranked rushing offense and the Cowboys had the top-ranked run defense.
The Eagles took the kickoff and drove 79 yards for their first opening-drive TD this season. Vick was sacked by Ware on the first play, but he connected with Jeremy Maclin for 24 yards on the next one. McCoy had a 21-yard run and Vick scrambled 15 yards to the Cowboys 13.
On third-and-9 from the 12, Vick tossed a screen pass to Maclin, who followed a lead block by Jason Peters into the end zone.
Vick led the Eagles 90 yards with McCoy running in from the 2 for a 14-0 lead. McCoy had runs of 11 and 34 yards before scoring for the seventh straight game. He's one short of Steve Van Buren's team record set in 1947.
Asomugha set up Philadelphia's third scoring drive by picking off Romo's pass at the Eagles 33 after the ball bounced off Martellus Bennett's hands.
Vick kept the drive going with a 9-yard run on third-and-8, and made a perfect pass to Jason Avant for a 20-yard gain on another third-and-8. He threw a strike to Brent Celek in the back of the end zone on the next play for a 9-yard TD and a 21-0 lead.
The Eagles had a first down at the Cowboys 6 on their fourth possession, but settled for a 23-yard field goal by Alex Henery that made it 24-0.
Henery kicked a 26-yarder to make it 27-0 in the third quarter. McCoy's 13-yard run put Philadelphia up 34-0 in the fourth.
But the Cowboys spoiled the shutout bid on the ensuing possession when Romo threw a 70-yard TD pass to Laurent Robinson.
