Here are the rushing defensive matchups for week 3. I think it is a little easier to judge how the rushing defenses are doing earlier in the season than the passing defenses. So I feel a little better about using these stats than the passing stats.
All of these numbers are rankings, not yards or fantasy points
Yds/Gm: Total passing yards given up per game
RB FPA: Fantasy points allowed to running back
Yds/c: Average yards per carry
