Redskins high defense and spread:

If the line moved a point and a half it's because there was either smart money or large wagering on the Redskins (god knows why, they stink) and the books move the line to get a 50/50 split on the action so they can profit from the Vig. They don't panic, they just adjust the line to get even action so they can profit no matter who wins the game. That's how Vegas is run.
They only panic when a million people have the same teams on parlays and they all cover, like what's been happening the first 8 weeks of the season, that's why Vegas is crumbling right now...
