Junkyard Dog
From the American Football Coaches Association's Defensive Football Strategies, the chapter penned by Erk defines the Junkyard Dawgs, "By our own definition, a Junkyard Dog is a dog completely dedicated to his task, that of defending his goal line. Further, he is very often a reject (from the offense) or the runt of the litter. Nobody wants him, and he is hungry. We had three walk-ons, four QBs, and three running backs in our original Junkyard Dog starting cast, which averaged 208 pounds across the front. In short, a Junkyard Dog is one who must stretch and strain all of his potential just to survive. Then he can think about being good."
