Excerpt from this article:
Since the late 1980s, the winning percentage of road teams has been rising in the NBA. After speaking to dozens of players, coaches, and team officials, Tom Haberstroh found a fairly accepted answer: “NBA players are sleeping more and drinking less”. Players are taking their careers more seriously and partying less on the road while transportation coordination has improved. Ubiquitous cameras and big sponsorships keep bad behavior in check. An additional factor is that with apps like Tinder and Instagram, companionship can be delivered to a player’s hotel room like Seamless or Postmates without the need to drink at the club for a few hours beforehand.
