So, now we know the Redskins defense will be coached by Jim Haslett, who has been a successful defensive coordinator and a occasionally-successful head coach in the NFL. There has been talk that head coach Mike Shanahan wants to run a 3-4 defense in Washington and Haslett played in and coached a 3-4 defense for many years. However, he's also coached the 4-3 defense and either is possible next season. The Redskins could also play a hybrid defense, switching between 4-3 and 3-4 depending on matchups and game situations.
