More than fast breaks or “SportsCenter”-worthy highlights, the Warriors subsist on wide-open shots. They are spread throughout the court and in constant motion. The ball darts from player to player with so much speed that defenders are left scrambled, only fully grasping what has unfolded after the shot is hoisted. Now, nearly halfway through the season, Golden State is trying to ride that movement-heavy blueprint into the record books. Entering Wednesday evening’s game in Dallas, the Warriors are shooting a franchise-best 50.8 percent from the field. They are on track to become the first club to have made more than half of its attempts in a season since the 2013-14 Heat shot 50.1 percent. The only Golden State team that accomplished that feat was in 1991-92, when Chris Mullin, Tim Hardaway and Sarunas Marciulionis powered the Warriors to a 50.7 percent clip in head coach Don Nelson’s pace-and-space system. Perhaps most startling this season is how it Golden State has gotten to its shooting efficiency. In recent years, as the league has put more of an emphasis on three-point shooting, teams’ overall field-goal percentages have dipped. However, the Warriors are managing to convert more than half of their shots while relying heavily on their long-range exploits.
