Matt Schaub was sacked five times in the game against the Redskins. I've been able to see all five of those plays via NFL.com.  One of them was all on Scahub, He held onto the ball too long, and when the pressure came, he could have stepped up into the pocket, but he broke out and was chased down, but  three of the others..... All involved Eric Winston.

Winston and Caldwell double team the DE, but when the ILB blitzes outside, Winston isn't able to get free and pick him up.

The Skins blitz the Safety and a CB against the right side.  There is a screw up between Winston and Caldwell.  Both are initially picked up, but when they stunt, Caldwell sticks with his man, but Winston tries to swap.  Landry gets free an hits teh Schaub.

Brisel can't handle a spin move on the overload blitz.

Dressen comes across to help block.  But someone misses the call.  Winston blocks left, Dressen blocks right and the Skins player in the middle goes straight through the gap and nails Schaub.

I imagine there will be some ribbing in the film room this week.
