With the Cleveland Cavaliers set to visit the Boston Celtics in Game 5 of the Eastern Conference Finals Thursday night, the 2017 NBA Finals matchup should be made official one week before the series begins. The Golden State Warriors punched their ticket Monday when they swept the San Antonio Spurs, and the defending champions are about to clinch their berth on the home floor of the No.1 seed. There has been little doubt since the start of the playoffs that the Warriors and Cavs would meet in June for a third consecutive year.
