In Game 4 of this year’s NBA Finals, the Golden State Warriors countered the Cleveland Cavaliers’ two-game winning streak by going with a smaller lineup full of more accurate shooters. That evened the series at two games apiece, with each time winning one game at home and one on the road. Now it’s Game 5, with the Warriors hosting from Oakland, and from here on in, if there is a home-team advantage, that advantage switches every game – a rule change that just might make a difference this year.
