Wide receiver James Thrash of the Redskins expects to lend more to the offense under new coach Jim Zorn.  Thrash seems to have the inside track on being the number three receiver for the Burgundy and Gold.  Zorn says he likes the fact that the team doesn’t skip a beat if Thrash is on for Santana Moss or Antwaan Randle El.  Washington is home to the Buffalo Bills Saturday evening for its first preseason game in Landover this year.
