To differentiate between all the "Start 'Ems" on my Fantasy Football Start Em, Sit Em page, you can check out the Weekly Fantasy Football Rankings, so you can figure out whom to start between Player X and Player Y.
Below are my fantasy defense rankings and a set of links for my positional Weekly NFL Fantasy Football Rankings. Keep in mind that this list is for this week only; not the entire rest of the season.
The rankings are based on a traditional scoring system. Each player has Walterfootball.com's projected stats and standard scoring points.
The Eagles are the top defense this week. They have a tremendous pass rush going against a rookie quarterback. The other Pennsylvania team, meanwhile, gets to beat up on the anemic Brett Hundley at home on national TV.
The Redskins should be available in your league. They don't have a good defense, but their matchup this week versus the Giants is an easy one. New York just won its Super Bowl, so I expect the team to be flat.
