ARLINGTON, Texas - Now Tony Romo knows what it sounds like to hear more than 100,000 people booing.
For all hype and pageantry leading into the first game at Cowboys Stadium, the largest regular-season crowd in NFL history turned against their star quarterback once he reverted to some of his error-prone ways.
"Obviously my mistakes really put us in a hole and allowed them to capitalize on some things. ... I really cost us," Romo said. "I'm sorry I wasn't able to play up to the level of the rest of the guys."
The Giants scored all three of their touchdowns after Romo threw interceptions, then Lawrence Tynes kicked a 37-yard field goal as time expired for a 33-31 victory over the Cowboys late Sunday.
A week after a career-best 353 yards passing and no turnovers in the opener, Romo had one of his worst outings in one of the biggest settings of his career: 13 of 29 passing for 127 yards in the home opener.
"I'm just really, really disappointed in myself right now," Romo said.
So were many in the packed house of 105,121 that included former President George W. Bush, NFL commissioner Roger Goodell and LeBron James.
Even with the mistakes by Romo, it was an incredible first game at the nearly $1.2 billion stadium: eight lead changes, neither team ever ahead by more than six points. The lead changed three times in the final eight minutes, and Tynes had to make the game-winner twice - Dallas called time out just before the snap the first time he made it.
"It was a big game, a division game," said Giants safety Kenny Phillips, who had two interceptions. "It was like their homecoming game. They picked us to play here. It's a big win."
