Mac’s lack of plan

Ben McAdoo refused to shed any light on Odell Beckham Jr.’s availability for Monday night’s Week 2 home opener against the Detroit Lions, but Beckham (sprained left ankle) did run some encouraging routes in his pre-game warmup at AT&T Stadium on Sunday before being ruled out in a game-time decision.

“He was out there working out in pregame, that’s all I have for you,” McAdoo said, when asked if Beckham’s condition has improved. “We’ll see, we’ll take it day to day ... He’s going to come in (the next couple days) and he’s going to get treatment and work with the training staff.”

Ben McAdoo can talk about “complementary football” all he wants and blame all three phases of his team for Sunday night’s 19-3 embarrassment in Texas. But it was the Giants’ offense — McAdoo’s offense — that let this team down again.

Not the defense. Not special teams. It was McAdoo’s offense, just like last season, the same old song and dance of three-and-outs, predictable play-calling and postgame compliments of the opposing team’s defensive coordinator and his game plan.

McAdoo still was calling this a team loss in his Monday afternoon conference call as the Giants began to turn their attention to a Monday Night Week 2 home opener against the Detroit Lions. But the coach at least began his criticism of Sunday’s defeat with his own unit.

“What we need to work on as a team, quite simply: play more offense, play less defense,” the coach said.

McAdoo has to improve as a play-caller and coach, however, as much as his offensive players need to step up.

It was Week 5 of last season when former Giants receiver Victor Cruz revealed in Green Bay that the Giants’ offense was unable to effectively attack Cover-2 defenses, also known as one of the most base defensive alignments in the sport with two safeties high. And then on Sunday night several Giants offensive players said that the Cowboys’ defense – which was suspect with many new faces coming in – had played a lot more zone than the Giants had expected, which affected their ability to push the ball downfield.

The Giants had only one 30-plus yard play from scrimmage all night (a 31-yard Evan Engram catch), compared to three for Dallas, and just five plays of 12 yards or more compared to the Cowboys’ 10.
