A single word can describe a lot of recent changes to the strategy surrounding multitudes of sports in recent times (and perhaps drum up some debate among sports fans): Analytics.
Data and the conclusions drawn from it have changed the look and feel of the biggest sports in the American popular conscience. Just look at the prevalence of 3-point shots on the basketball floor or the reliance on relief pitchers on the baseball diamond for evidence. Of course, it goes well beyond on-field strategies; analytics can also inform teams on broader-scope elements of their organization like scheduling, roster construction and so on.
