The Cowboys opened its 2012 campaign at MetLife Stadium in the Annual Kickoff Game against their NFC East foe, the defending Super Bowl champion New York Giants.  After a scoreless first quarter, the Giants picked up the season's first points as kicker Lawrence Tynes kicked a 22-yard field goal in the second quarter.  Dallas would close out the half with quarterback Tony Romo finding wide receiver Kevin Ogletree on a 10-yard touchdown pass. In the third quarter, the Cowboys added onto its lead Romo hooked up with Ogletree again with a 40-yard touchdown pass.  New York answered with a 10-yard run from running back Ahmad Bradshaw, yet Dallas responded in kind with a 33-yard field goal from kicker Dan Bailey.  The Cowboys pulled away for good in the fourth quarter with Romo connecting with wide receiver Miles Austin on a 34-yard touchdown pass.  The Giants closed out the game with quarterback Eli Manning completing a 9-yard touchdown pass to former Dallas tight end Martellus Bennett.
