Dolphins coach Tony Sparano is preaching the concept of team defense. "I think they're starting to understand a little bit more about the total concept of team defense," Sparano told the Miami Herald. "Meaning, it doesn't have to end up a sack every play. It doesn't have to end up an interception every play. "And yet, the end result can still be pretty good." The Dolphins are facing the Saints this Sunday, who average the second most yards per pass play in the NFL this season. Meanwhile, Miami has allowed the second-most yards per passing play.
