It has nothing to do with people not liking sports as much or missing the Olympics due to Facebook/Twitter/snapchat and everything to do with the fact that they beholden to this prime time nonsense and think that millions of people are willing to watch events when they already know what happened. Sports can be great storytelling devices but being able to watch live and see what happens with everyone else is a major part of its appeal, and why networks are paying more and more to the major leagues.
