Which DEFENSE for week 6 and why?

I would stick with Arizona for this week, particularly if your league has a fee for doing add / drops. Carolina with David Carr is like facing the 2004 Texans, which sucked by the way. Steve Smith should be the focus for the Cardinals and he can be double teamed. If Zona rushes E. James and controls the ball with Warner picking his spots, Carolina will be in a catch up mode all game. Hold what you got.
