Earlier this NFL season the Miami Dolphins defense was getting credit for having addressed its issues of a year ago, and new defensive coordinator Matt Burke was being profiled as an upgrade form Vance Joseph. It was a great time because some folks were expecting the early success to continue and this defense to carry the team into the NFL playoffs.
Except any season ebbs and flows and sometimes units improve and sometimes they get exposed.
And lately the Miami defense is looking more like the latter.
