I'm really pulling for the Spurs to keep this particular stat going. The teams making the finals always have one or two things that they do better than anyone else in the league statistically (rebounding, 3pt shooting, etc), and being a top team on the road is a great indicator of playoff success (or toughness at the very least).
I remember the Spurs used to be high on the list of road wins each season, and its exciting for them to have that in their mentality once again. Mother ing road warriors.
