Enveloped by the black hole that is TD Garden, the Heat’s winning streak was stretched to the edge of oblivion Monday night. Stars go to die in Boston, but not LeBron James. He owns the place. Just like the 2012 playoffs, James shot down the Celtics in their own building to keep the magic alive. Last season, it was the hopes of an NBA title. On Monday night, it was the dream of catching the Lakers for the longest winning streak in NBA history.
