Breakdown: The Dolphins will begin this season with playoff expectations after last year’s 8-8 finish. But in order to make the postseason, Miami must get through a competitive schedule that includes six games -- Broncos, Chiefs, Packers, Chargers and Patriots (twice) -- against playoff teams from a year ago. It also will be interesting to see how the Dolphins handle their long trip to London to face the Oakland Raiders in Week 4. But perhaps Miami’s biggest hurdle is within the AFC East.via - NFL Nation
