The top of the chart has the worst defenses and the bottom the best. So as you can see in the first row of the passing defensive chart Tennessee and Detroit rank worst in our total. And then you take a look at their opponents, Seattle and San Francisco (both at home by the way), and you can feel pretty good about playing Crabtree and Burleson and their bretheren. So the teams on the far left column are the defenses and then just right of them are the offenses with your fantasy players hidden in there somewhere.
Take a look and if you have any questions be sure to ask!
