White extends the laser and begins circling No. 24 at the top of the screen. "Look at Nnamdi," he says. "He likes to get in your face, jam you, disrupt routes that way. He likes to be down at the line of scrimmage and get his hands on you and disrupt the timing. With a guy like this you really have to use your feet. You have to give yourself some room against him. Even if you're on the open side of the formation, you can back off the line by a half yard because all the officials require is that you cover up the tackle on that side. This guy right here ..." White circles the receiver Asomugha is preparing to press. "... He's doing a bad job, to me, because I would never have been this close to the line of scrimmage," Roddy continues. "Nnamdi's arms are so long that it makes it very easy for him to get his hands on you. That's his comfort zone. So you back this out a half-yard, get some distance and prevent him from getting his hands on you. And with a guy like him you've got to use your feet -- hands and feet. You've got to get ready and put your hands up quickly because he's going to launch at you and try to put his hands on you to disrupt routes. So you always have to be going forward and your hands in a position to be above his, because if you can get his hands away from you, then you can pretty much dominate."
