Besides the fact that Dallas and Oakland are still alive in the postseason race, their respective histories make this a faceoff of iconic brands. The ironic side of that is, despite all of the shared success, the Cowboys and Raiders have never shared a Super Bowl field. What really makes that (black) hole in league history fascinating is that each team was in its league/conference championship game in 1967, 1970, 1973, 1975, 1977 and 1980 -- and yet, not once did both franchises advance. That last season, Al Davis' Raiders won it all, but Dallas had taken them down in December.
