The Washington Redskins' hunt for a new defensive coordinator is off to a flying start.  

Head coach Jay Gruden fired four people in the defensive side of the ball, and he's wasting no time in his search to replace everyone.

The Redskins announced Monday that they interviewed former Cleveland Browns head coach Mike Pettine for their vacant defensive coordinator position.

Before taking the head coaching job in Cleveland, Pettine was Rex Ryan's defensive coordinator from 2009 to 2013. In his time under Ryan, Pettine never had a defensive unit that finished outside of the top 10 in total defense. 

Though there are other deserving candidates for the position, Pettine is one of the most well-respected defensive minds in the NFL and has a proven track record of success as a defensive coordinator. 

If the Redskins decide to hire him, it'll be a good start to turning around their 28th-ranked defensive unit.
