When the Miami Dolphins added Matt Burke to the coaching staff it made sense. He was a linebackers coach and did a good job in 2016 with a unit that was depleted of talent. The Dolphins defense played well enough that year to get to the playoffs but the defense was run by Vance Joseph.
In 2016 Burke became the defensive coordinator and the Dolphins had some good games but mostly bad ones under Burke. Many believed that Burke would grow into the role but that too has shown to be a falsity. This year the Dolphins defense which arguably has more talent than last season is near the bottom again in league statistics.
