Fantasy FB RB's & WR's for week 4?

I think you got it right. While it's true that McNabb will be fired up, nobody knows how to defend McNabb better than the Eagle D. The Redskins have no credible rushing game and only 5 teams have given up fewer fantasy points to opposing WRs than the Eagles. Walter has a decent matchup. Johnson has an ankle injury and may or may not play this week. Even if he plays, he'll be covered by one of the best defenders in the NFL which leaves the other receivers to get a lot of looks this week.
