I think the Saints were really taken by surprise, in the 1st game vs. Tampa, by how well Gradkowski played. We really didn't know what to expect from him, having it be his first start. He played very well, and they allowed him to throw the ball more than expected... That's why they were able to hit so many big plays on us.
We were clearly the better team. I just think they surprised us. If they were going to beat us this year, that was their chance. This time around we know better. :)
