DC Joe Barry is out in D.C. The Redskins are firing their defensive coordinator along with the rest of their defensive staff, Jason La Canfora of CBSSports.com tweets. 
Barry has had only two years in Washington, but in that time the Redskins have finished near the bottom of the league in yards allowed. Prior to joining the Redskins in 2015, Barry’s only previous experience as a DC came with the Lions in 2007 and 2008. With Detroit, his defenses finished dead last in yards allowed. In between the two jobs, he had stints as a linebackers coach for the Buccaneers, USC, and the Chargers.
Two years ago, head coach Jay Gruden chose Barry over Wade Phillips. Now that the Broncos and Phillips could be parting ways, Gruden could take this opportunity to reverse that decision. Whether it’s Phillips or someone else, the next DC will have intriguing pieces to work with, including cornerback Josh Norman, linebacker Mason Foster, and utility man Su’a Cravens.
Do the Skins run a 3-4?
Yes indeed, 3-4 base with option to run 4-3 type setup with 1 or 2 of the OLBs as a down DE
This D has really stunk it up… very slow at inside LB and very slow at Saftey … went out and spent a ton on Norman, and it had very little effect
