PHILADELPHIA -- Defensive coordinator Rob Ryan takes all the blame for the Dallas Cowboys' failure to back up his big mouth.

Ryan mockingly referred to the Philadelphia Eagles as the "all-hype team" during training camp and vowed that the Cowboys would "kick their ass" when the NFC East rivals met. The opposite happened Sunday night at Lincoln Financial Field, when the Eagles scored on their first six possessions while rolling to a 34-7 rout.

"The whole thing is I got outcoached by [Andy] Reid and their staff," Ryan said. "I mean, it's ridiculous. I never gave our guys a chance. The whole [expletive] thing was on me. If I gave them any extra motivation, hell, I certainly never backed it up. I gave our guys a lousy plan. We had no chance, and it's all on me."

A Dallas defense that entered the night as the NFL's fifth-ranked total defense was absolutely dominated by the star-studded Eagles.

Philadelphia finished with 495 total yards, 324 of which came while racing to a 24-0 halftime lead. The Eagles rushed for 239 yards, more than three times the league-low average allowed by the Cowboys in the first six games of the season.

Eagles running back LeSean McCoy carried 30 times for 185 yards and two touchdowns, racking up the most yardage the Dallas defense has allowed in 11 seasons.

Quarterback Michael Vick completed 21 of 28 passes for 279 yards and two touchdowns and rushed for another 50 yards on seven carries.

The Eagles' first three possessions were touchdown drives of 79, 90 and 67 yards. The first score of the game was a glaring example of Reid winning the X's and O's battle. A quick screen to Jeremy Maclin, which resulted in an easy 12-yard touchdown, was a perfect counter to a safety blitz that Ryan called for the third time that series.

"Andy Reid was reading my mail," Ryan said. "He kicked my ass. I've just got to go back and work harder. I've got to be smarter than this. That's all it comes down to."

However, Ryan said this humiliating loss wouldn't make him watch his mouth in the future. That's simply not the style of the son of brash ex-Eagles coach Buddy Ryan and twin brother of Super Bowl-guaranteeing New York Jets coach Rex Ryan.

"Hell, if I don't say anything, then I don't really believe," Ryan said. "Hopefully, it will be the last time it ever happens. But whatever happened, it was all my fault."
