There’s film of the first Cowboys/Packers NFL Champ game, as there is for all such games since at least 1958. However, that first C/P game has never been considered — other than by Cowboys and Packers fans — to be a particularly iconic NFL moment, as the Ice Bowl has become.
Similarly, we always see replays of the Jets beating the Colts in SB III, but rarely ever see film of the Chiefs knocking the snot out of the Vikings in SB IV.
Well many of the older games simply dont exist, on film or video, there may be clips of the game, that probably were found at some newstation.
Highlights or short clips, is all that exists for many games, there is no whole video of the whole game.
Even the first 2 SB's dont exist as a whole game.
I had nfl game pass, and they had a SB archive, which many many games were simply not there.Some that were missing I have found on you tube
so they didnt make a lot of effort when compiling their archive, or had a quality standard that was too high.
Thier regular season archive starts in 2010 or 11, and is missing some games from the first year, so since then they have been archiving all games
as complete games, before that, they probably only archived games they saw as unique in some way or just highlights.
It was the fans themselves, and thanks to the good ol vcr's ! that archived a lot of complete games. The nfl has the money
and the ability to get those games from fans, and then archive them , but they have made no effort, and I think are too cheap and stupid to do that.
