Will the defense be fired up?

Our defense is just out-classed at times. Hollis Thomas has done a great job stuffing the middle but when Willie started breaking runs outside, there wasn't any run support. I like a lot of the guys on our D, but a lot of them need to be replaced with better athletes if we're going to be an elite team. They'll be fired up on Sunday, but if we don't pressure Palmer, our corners are gonna have a rough day against Chad Johnson and TJ Houshmandzadeh.
