I understand the reasoning and it's totally fine and informative for discussions like this one where you can dig into what a particular grouping means in terms of down/distance in context...I just think on TV it's unnecessary.
Not really. Over broadcast announcers used to refer to 'two tight-end sets' or 'coming out w/3 wideouts' or whathaveyou all the time...it only bugs me to the extent that I prefer plain language over technicalities.
