The Eagles will look to simplify their defense under new coordinator Juan Castillo. Castillo has been unable to work out with his players because of the lingering NFL lockout. "It allows us to be more thorough with our playbook and our defensive plan," Castillo said of the time off. This week, for example, he and his staff hashed over what blitzes to use on third downs and how to make the concepts easier to teach. "Jim Johnson got some great blitzes. I want to have them all in the package, but how can I do it here so that it's simple for my guys so that everybody can understand," Castillo said. "To play fast, you can't be thinking."
