Buddy Ryan built a great defense when he took over as head coach of the Eagles back in 1986. It took him a few years to put all the pieces together, but Gang Green's performance in 1991 is one of the best of all time. Unfortunately, that particular defense didn't get to the postseason. It would have been great to see them playing in January for the one season that everything truly clicked. Instead, we are left with frustrating memories from 1988, 1989, 1990, and 1992. Reggie White and his teammates couldn't shut people down, allowing 20 or more points in each playoff game in those seasons. Despite enormous talent, those teams only won a single playoff game. Jim Johnson had some great defenses.
