They have lost games by 18 points and dropped some by two. They have been out of games in the first half and been half a minute from victory. But in the end, no matter the players or coaches, the Redskins lose in Dallas. For nine straight seasons that has been the case, and the Cowboys' hex is as strong as ever after last December's 13-10 win, when Washington was one play from victory and nursing a four-point lead. Most of the players on the Redskins have limited direct involvement in this fierce rivalry, but everyone in the organization knows the depths of this losing streak, its significance and the apparent mental block that has accompanied it. Getting over this hurdle will not be easy, particularly after the heartbreak of last year's loss.
