Justin Tuck now has two big diamond rings on his finger. He also has room for many, many more.

That’s the lofty goal the Giants are setting as they get ready to defend the fourth Super Bowl championship in franchise history. Winning two in five seasons was an incredible accomplishment, but they want something bigger.

They want to be a dynasty, too.

“I think the second ring makes you that much hungrier,” Tuck said on Wednesday night as the Giants got their Super Bowl XLVI championship rings at Tiffany & Co. in Manhattan. “You get there the first time and you’re in awe. You win the second one and you’re like, ‘Hey, Maybe we can do something here.’

“Our thing now is we want to be a dynasty. We want to make it a dynasty.”
