After initial reports indicated new Buffalo Bills head coach Rex Ryan would likely retain Jim Schwartz as the club's defensive coordinator, the Bills and Schwartz will now part ways. Instead, Buffalo will use Dennis Thurman, who served as the Jets' defensive coordinator the past two seasons under Ryan, in the position.
This could open the door to a potential move for the Miami Dolphins. While everything has been quiet around the South Florida franchise recently, at least in the coaching front, speculation as the season ended had defensive coordinator Kevin Coyle's job at least in question. No word has stated that Coyle is either safe or on his way out.
Schwartz ran the fourth ranked defense in 2015, the third ranked passing defense, the 11th ranked rushing defense, and the fourth ranked scoring defense. Miami could use an upgrade to their defense, especially after having watched the defense fall apart down the stretch this past season.
It's complete speculation, as there is absolutely nothing saying the Dolphins are even considering a change at defensive coordinator. It could, however, be an option with a top-flight defensive coordinator suddenly on the market.
