I just use the regular redskins def playbook. The 4-3 is good at stopping most runs because all 3 linebackers are fast and Haynesworth is a beast in the middle. Also, in the Dime package, switch it to the linebacker pass rush package. That puts Orakpo at one DE and Macintosh at the other DE. Good speed to get pressure with just 4 guys. The best pass def play I found in the Dime normal is cover 2 buc.
