With FA nowadays & the greed of players, it's getting tougher & tougher to see a dynasty ever happening again. The 70s Dolphins went to 3 straight SBs due to the fact that they were able to keep almost all the core starters every yr. Same for late 70s Steelers. The 70s Cowboys also managed to keep many core starters from defecting & along with the Steelers & Miami, appeared in just about all the SBs of the 70s.

While the Raiders didn't win but 1 SB in the 70s, they were in the vast majority of AFC title games & so were the 70s Cowboys. Shame the Raiders & Cowboys of the 70s never met in a SB. Woulda been epic!
