It is often said that one of the keys to success in the NFL is having a great QB/RB/WR trio. Although defense wins teams a championship in many cases, having a great trio at the skill positions on offense certainly can't hurt. Some might say that teams like the 49ers of the '80s and the high octane offenses from the Bills and Cowboys of the '90s set the tone for what football fans are seeing today. These three franchises put an emphasis on building their teams around these positions.
