New York Giants coach Brian Daboll didn’t mince words after reviewing the film of his team’s 40-0 loss at home to division-rival Dallas on Sunday night.”It was a collective effort,” Daboll said on Monday, following an admittedly restless night of sleep.”There were a few things you can build on but when you get beat like the way we got beat, no excuses. I’d say there’s a lot of work that needs to be done, a lot of corrections that need to be made and that’s what we’ll do today.”After a promising opening drive stalled in the red zone following a penalty and a fumble that the Giants recovered, the Cowboys blocked a field-goal attempt and returned it for a touchdown.It was suddenly 6-0, and the avalanche had begun.By the end of the night, Dallas had outgained New York 265-171 and produced three turnovers and seven sacks to the Giants’ none in either department.”After a game like last night, every area we’ve got to draw our attention to,” Daboll said. “You take it for what it’s worth. It was a poor performance. You learn from the things that you can learn from and then you really got to get focused on the next week.”Week 2 provides what on paper looks like a very winnable game at Arizona. That kicks off a three-week stretch against NFC West foes that includes a trip to San Francisco before returning home to play Seattle in Week 4.
