Tom Brady has described the New York Jets' defense as "one of the best defenses in the league".
The New England Patriots play their AFC East rivals for the first time this season on Thursday night.
The quarterback told reporters: "They've always had one of the best defenses in the league. It's really a challenge every time that we play them. I think they do quite a few things. They have a lot of different looks, a lot of different personnel packages. They really keep things moving on defense. It's a good scheme.
"They're a very well coached, very disciplined, very smart defense. They don't make many mental errors. It's going to be a great challenge for our offense. They rush, they cover, they blitz. The guys have different skillsets. They can all do a lot of things. It's a very good group.
"They have a lot of good players. They're very well coached, they're smart, they're disciplined, they're physical. They do a lot of good things and we have a lot of respect for them as a team and their coaching staff and the players that play there."
Both teams won their opening games of the 2013 NFL season on Sunday.
