Defense hasn't been the biggest problem with the Miami Dolphins the last few seasons. The unit ranked in the top 10 in total defense, and was tied for second in red-zone defense, in 2010. Last season, the unit dropped to 15th overall, but remained one of the toughest defenses to run against and ranked sixth in the red zone and scoring. With the team moving from a 3-4 to 4-3 defense under first-year coordinator Kevin Coyle, members of the defense think the unit has a chance to be special, Izzy Gould of the South Florida Sun-Sentinel reported Sunday. We've got a chance to be great," middle linebacker Karlos Dansby said. "We have a chance to be great in this defense. We have enough skill set. We have enough talent. We can make this defense work for us." Source: NFL.com
