SAN FRANCISCO (AP) — A peek at Golden State’s practice Saturday wouldn’t have suggested that the Warriors are trailing the Boston Celtics in the NBA Finals. Stephen Curry was making most of his shot. Klay Thompson was bobbing his head in time with the music in between his own shot attempts. Draymond Green was at the other end of the floor with the forwards yelling “Oh, yeah!” at nobody in particular. The biggest game of their season is Sunday. They don’t seem nervous about it. The Celtics can take a 2-0 lead of the NBA Finals on Sunday when they visit the Warriors.
