Wow! Some of you guys are really old. And, you actually remember where you were when it happened!
I was in the Bronx, with my family, visiting my paternal grandmother and celebrating an early Christmas.
We would spend Christmas Day (two days later) with my mother's extended family.
It was like two Christmas-days for a boy but the highlight was not the presents ... it was the food. My grandmother spoke little English and cooked only Italian dishes but ... Mother-of-God ... that was some of the best Italian food I have ever eaten. My sisters and I would take the meatballs out of the frying-pan and eat them with our hands ... like Animals! They were perfectly crunchy on the outside but moist and tender inside.
My sisters still discuss them all these years later. They're kind-of-old, like some of you guys.
As for the play, I remember the conversation about whether Raiders' safety Jack (They Call Me Assassin) Tatum contacted Bradshaw's pass attempt to John "Frenchy" Fuqua. Lots of people thought the ball only hit Fuqua, who was drilled by Tatum. knocking the ball into the air for Harris to (maybe) catch it before it hit the ground.
Back then, there was a rule that if two offensive players touched the ball, without a defensive player getting his hands on it in-between, the pass was incomplete. If Tatum did not touch the ball, the question of whether Franco Harris caught the ball would be irrelevant.
