When a puck goes into the net---actually it goes between the goal posts, not into the actual netting---a goal is scored and one point is awarded. I suppose, by a very loose linguistic interpretation, that the puck in that case could be considered to be a goal. "Puck" and "goal" are used synonymously in this crossword. In basketball, when LeBron James (for example) successfully makes a three-point shot, the announcer will often say "James shot a three" when we all know that what James actually shot was the basketball. (On a related note, why do people say they walked through a door when they actually walked through a doorway?)
