The Miami Dolphins today continued to purge their coaching staff as Kevin Coyle was fired after 68 games with the team.
In Coyle's time as defensive coordinator the defense steadily regressed on multiple fronts, most importantly in giving up more points with each passing year. Before Coyle arrived, the Dolphins allowed an average of 19.6 points per game.
But Coyle was hired by former head coach Joe Philbin and converted the 3-4 defense into a 4-3 unit. And that unit allowed an average of 19.8 points per game in 2012, then 20.9 points per game in 2013, then 23.
