Seems to me if Spike never showed up and Icebox played the whole game

Sounds about right. I mean I can't be the only person who thinks that the Cowboys should have been up a lot more than 21-0 at halftime. But yeah the Giants had two players that could actually play: Becky and Junior, add one good player back to the Giants and take away a good player from the Cowboys then yes the Giants would have won easily going by this movies logic.
