I agree with you that there's no real imperative for a sports league to need to "keep up" with technology.

But one possible way to look at this is as a regulation on what technology coaches can or cannot use currently as they please. E.g., defenses playing against teams who run no-huddle offenses usually have no time to call plays or change the defensive scheme, and thus allowing the defensive captain to update and change plays at the line could be a huge plus for teams that _wanted_ to do this but currently cannot.

Forcing coaches to use iPads on the sideline for the hell of it is silly; prohibiting teams who want to analyze film in realtime on the sideline or instantly communicate plays on the fly who wish to do so is a bit different.

Allowing such communication changes the tradeoffs of such a strategy. How are you concluding that one set of tradeoffs is "correct"?
