I was looking at videos of how the Packers Cowboys 1966 NFL championship was very close (as was the Ice bowl the next year) and I couldn't help but think the former Dallas Texans/Kansas City Chiefs would have been more pumped to play their former crosstown rivals. I also saw a near 'miss' of this match up in for Superbowl 6 (Chiefs missed a last second FG and then lost to eventual AFC champion Dolphins in double OT).
I was wondering what other interesting match ups you could come up with.
