He pointed out the positive takeaways on defense from the Raiders loss to Green Bay last week.

"It's good for us to go up against teams that have been pretty good and at the same time match up to see where we stand. That was a good offensive line, good running back and it's important that we learn that you have to come out ready to play, even though you're in the right spot, you have to make plays. But, we can't let that first drive [happen]. The guys played really good later on, the second drive, the third drive, they really recovered after that first drive."

The second-year defensive coordinator expects the defense to be tested this week against the Titans.

"You want to see where your strengths are. You have a thought about what your strengths are, but then you actually play the games where you find out where your true strengths are. We'll see how good we are and [where] our run fits and our energy and effort, our ability to play a mobile quarterback, because you have to be good against the run, you have to certainly contain your quarterback and you have to play good solid ball, good fundamental ball throughout the game consistently."

Norton has been pleased with the progress of rookie safety Karl Joseph, and noted his goal line stop on Packers running back Eddie Lacy.
