Stephen Curry scored 37 points, Kevin Durant added 20 and a triple-double and the Warriors stamped themselves a dynasty after winning their second straight NBA title and third in four years Friday night, 108-85 over the Cleveland Cavaliers to complete a sweep and perhaps drive LeBron James from his home again to chase championships. Overcoming obstacles all season long, the Warriors were not going to be denied and won the fourth straight finals matchup against Cleveland with ease. It was the first sweep in the NBA Finals since 2007, when James was dismissed by a powerful San Antonio team in his first one.
