Interestingly, we don't even have to time travel all the way back to Osaka.
Remember Buffalo.
No, the thing to remember about a result like last night is, if they'd lost and looked bad doing it, the message boards and talk shows would have been going nuts and pretty much burying Shanahan and the Redskins. Since they won and looked pretty good doing it, the reaction SHOULD be equally over the top in the other direction. It won't be, of course--that's not the way the world works--but it should.
We have a week to feel pretty positive, and so does the team. Beats the hell out of a week of feeling apocalyptic. But in the end it's still just preseason. We won't really "know" anything about this team until opening day.
