In a move that would be the first of its kind in sports history, the NBA is close to signing an agreement that would let cable customers stream their local teams online, for free. It’s a bold play by both the NBA and the TV networks involved, as it’s a drastic increase in services at no cost. Nonetheless, given the pace at which options like Aereo and Roku are encouraging young cable subscribers to cut the cord, it’s a concession to the simple fact that expectations are changing: sports fans increasingly want to live-stream games, wherever they are, on whichever device is suited to that moment.
