'Last Sunday, Fletcher Cox and the rest of the Philadelphia Eagles' D-line proved to be a nightmare for Buffalo's blockers. On multiple occasions, Cox simply overpowered the man in front of him. That made for a particularly long day for guards Richie Incognito and John Miller, who, when Cox wasn't blowing past them, were being penalized for holding him. That did plenty to limit the effectiveness of the Bills' offense and cause it to move with an uneven tempo throughout the game. This Sunday, the Bills are going to face a Redskins defensive line, anchored by tackle Terrance Knighton, that is every bit as capable of making life miserable for Incognito, Miller, center Eric Wood, left tackle Cordy Glenn and right tackle Jordan Mills (who is expected to start his third game in place of Seantrel Henderson, who is battling Crohn's Disease).'
