My theory on tonights game... and Cousins development so far...
The Giants do not have a great Run game. However their Run Defense has been pretty stout over the first two games. They've actually allowed less running yards than we have. Even the Cowboys vaunted O-Line couldn't help the Cowboys get more than 80 yards rushing and Randle only had 65.
We've modelled our O-Line somewhat on the one in Dallas, only we're a year behind. But we have looked REALLY good in the first two games. (Though with Moses and Scherff being practically rookies on the line - know Moses is a 2nd year, but he was in IR all last year if I recall - I'm kinda still waiting for a repeat of the Detroit pre-season showing.) If we're solid then I don't think the Giants have faced anyone with a 1-2 punch like we have with MoJo (assuming they keep up the good work).
Gruden has shown commitment to the ground game so if he sticks to his guns I think we could have a good showing.
With that in mind and getting back to Cousins, he really just needs to do what he did last week. Manage the offense, not try and go for broke and trust our Defense to win their side of the ball.
The good news for Cousins? The Giants are ranked 32nd in the league in Pass Defense over 2 weeks. (They've allowed 702 yards through the air to Washingtons 328 yards. We're number 2 by the way!

)
Now granted they have faced Romo and Ryan, while we only had to contend with Tannehill and Foles, but still. Huge difference in stats.
They're also without Rodgers-Cromartie. So if Cousins plays calmly and sensibly there could be a big day for the passing game in prospect. I just hope that they still use the pass game to supplement the run and not vice versa.
The potential spoiler?
Eli Manning throwing to Beckham. Eli is not having a great season thus far, but Beckham is and while I think our cornerback and saftey play is improved... it still concerns me back there. (Thank GOD Amerson is gone!)
They've also led in both games going into the 4th quarter. Now Ryan and Romo are calm enough and veteran enough to spark comebacks....
Do we trust Cousins yet to do the same? Or Gruden for that matter.
Will they try and turn to the pass game for quick scores? If that happens will Cousins make it or break it under that pressure?
I think he's a better QB than a year ago, and I'd like to see him tested like that at some point. But maybe later in the season when he has more positive games and experience under his belt.
