They learned the hard way.

After the Giants’ shocking win over the Seahawks last weekend, Seattle cornerback Shaquill Griffin was asked Thursday about what went wrong for his team.

“I just feel like we let that game kind of get the best of us, and we came in taking a team lightly,” Griffin told reporters. “That’s just being totally honest. In this league, you can lose to anybody. It don’t matter who it is. It don’t matter if they lost every single game. You can lose to anybody in this league if you don’t play right. And I feel like we took that game lightly, and I feel like the focus point now is just refocusing, treating every team the same, treating it like a championship game like we continue to preach about.

“Understand that that team was not supposed to beat us. Let’s just be totally honest. They was not supposed to win that game, and we had to live with that. That’s a taste in our mouths that no one never wants.”

Backup quarterback Colt McCoy had not won a game as a starter in six years, and the Giants managed to ride their defense and running game to a remarkable 17-12 victory.
