I enjoy football and don’t know all the technical rules. However, with this discussion and others like it, I get the impression that replay review does not solve the problems of questionable calls by officials. It seems to add another questionable call when the replay referee overrules the referee on the field.
There will always be ambiguities that cannot be resolved definitively - if the rules covered all possible situations unambiguously, the rulebook would be an infinitely large volume.
About the only games I watch are when the Patriots are in the super bowl, but it seems to me as if video review pretty well handles the worst controversy in most sports, because it gives a closer look and aligns decisions with what the fans see.
Dallas fans are just big crybabies.
