I hear what you're saying, but I think it is always implied in discussions such as this that the best players or teams were "state of the art." I'm not sure the comparisons are ever apples to apples in sports because of the ever changing "state of the art." There are vast differences in any of the major professional sports within a decade, let alone comparing eras that are decades apart. Lining up the 60s Cleveland Browns and the 2010 Carolina Panthers and saying that the Panthers would probably win easily is like saying Edison's discovery of the light bulb pales in comparison to the development of the computer chip.
