I was listening to Fox Sports radio a few weeks ago, and they brought an interesting point up. When a coach has extended success in the NFL, they start to believe that it's all their system and not the players at all. Now good coaching can make players look really good, but you need to be able to put players in a good position to succeed. Shanny really hasn't done that with the Redskins and instead has just made moves IMO to just make moves. He made a lot of poor decisions towards the end of his days at Denver, and they're showing up in Washington again.
You need to have a plan when you're revamping a team and you have to have your players' skill set in mind. Shanny has been trying to fit square pegs in round holes the last 2 years.
Just for a reference, he is on pace to have a worse 2 year record than either Jim Zorn or Steve Spurrier.
