The Dolphins are focused on becoming a stout unit once again, starting with physicality.
"We have a physical defense," defensive end Jared Odrick said. "You've seen it last year.
"We talked about it all day [Sunday] at practice, how physical of a group we are up front," he added. "It's something we need to bring out of ourselves."
Miami was hoping the defense would carry the team this season, but they have struggled in their two preseason games.
"If you watch the film, there were guys there to make the play, and we didn't," said Dolphins coach Joe Philbin. "We had too many mental errors, we had too many missed tackles, stuff that beats you in football."
