I run the 3-4 defense with the Pittsburgh Steelers. Their strongest defense is of course the nickel, because of the speed of the Steelers linebackers. But it causes problelms whenever you are faced with a 4 wr because the slot receiver is picked up by a linebacker which we all know is a mismatch. What I need is some help with the defense. I get hit a lot over the middle. I tried using the dime under man but if they motion the running back to the middle, he's always open. Need some advice.
