Before free agency came along, the NFL was a land of dynasties. Teams could be built over years with no chance of star players escaping to other teams for more money. Those franchises that knew how to evaluate talent gained a huge advantage on the field, and their win streaks weren't measured in years but decades.

From 1966 to 1985, the Dallas Cowboys had 20 consecutive seasons with winning records. They made the playoffs 18 times, appeared in the Super Bowl five times, and were world champions twice. Along the way, they picked up the nickname "America's Team". Other franchises that earned the "dynasty" moniker were the Dolphins, 49ers, Raiders, Redskins and Steelers. Each year, those five teams seemed to vie for the championship. From 1971 to 1995, they won 24 of the 27 Super Bowls played.
