You are missing the point. Dallas kept them out of the endzone sure but that's also because they elected to not try and get in the endzone when they should have. Giants willingly made the choice to not attempt it. Dallas does not get credit for a choice the Giants made.But Dallas's defense kept them out of the endzone all game. No reason to believe it would be different on a 4th and 3 imo
Granted, if the refs weren't completely fucking retarded ont he first drive, the GIants chances of getting it in the endzone would have been pretty good, if they hadn't got penalized mistakenly for a facemask that should have been called on the cowboys 30 yard swing that resulted in a FG, instead of knocking on the door of the endzone.
