OP's comments are valid, however they are if's and actually the game is a win for Dallas and a loss for NY.

Every team makes mistakes all the time; this time the Giants seem to have made more relevant ones that the Cowboys. But it's part of the game. Dallas took advantage of it and this is necessary too for winning games.

Maybe the Giants will play better their next games, but maybe also the Cowboys. All teams are starting and making changes, adjustments and training.

I didn't watch the first game, but I can conclude, having read the posts about it, that the Cowboys played worse in that game, regardless of the rival.
