Parker explained that it's not about inventing some new defensive scheme, but about being schematically sound: "You only have 11 guys out there. When they are balanced, you have to play five and a half guys on one side and five and a half guys on the other side." If the offense is unbalanced, with additional blockers or receivers to one side or the other, the defense must "match" them and not allow the Ducks to get extra numbers or leverage. "You have to change up how you are covering it," Parker explained. Being sound is the most important thing. "What they are looking for is for you to make a mistake."
