The handoff between quarterback Joe Pisarcik and Larry Csonka was fumbled and Eagles cornerback Herman Edwards grabbed the loose ball and returned it [26 yards] for the winning score. Thank you for posting that. I remember watching the game with my father, a diehard Giants fan, yelling at John McVay about the call even before "The Fumble". All Giants fans were infuriated because the team was fighting with the Eagles for last place for a decade, and here were the Eagles moving up in stature with the Giants still going nowhere.
Fans burned their tickets en masse outside the stadium, called NBC (the AFC carrier then) and told them to NOT carry the Chiefs@Giants game because the Giants didn't DESERVE to be televised (Channel 4 New York cooperated, and showed a better game). McVay was fired soon after and Ray Perkins came in and started the turnaround. Giants fans in the '70s suffered from a massochism on par with Cubs fans from the same era.
Here is a good full color clip on "The Fumble".

You’re welcome, and thank *you* for the longer clip.
My late father was also a big Giants fan. I went for the then Baltimore Colts, despite our living in New York City for all of my life. Still there now.
