In the 1960's AFL days, Hank Stram ran a tripple stack defense. The DL was positioned as LDE over the tight end, LDT over the left tackle, the RDT over the center, and the RDE over the right tackle. I see many teams use this DL formation, also called a KC front. The LB were set like this : the LLB was behind the the LDT, the MLB was behind the RDT, the RLB was behind the RDE. In a coaching clinic I was told that it suts down the strong side runs. The LBers were in a better position to get into their zones, and the LBer reads were better. Now when you have Willie Lanier, Curley Culp, Buck Buchanon, Emmit Thomas, Aaron Brown, Bobby Bell you can play any defense you want. The biggest problem with this defense is that you can cut off the LB pursuit with angle blocking.
