Plexiglass instead of netting. Interesting idea, however, as a former goaltender, I'd hate to have to stand up my water bottle. Or, have a fear of the water bottle rolling off the net if I place it down on it's side. For the NHL, I don't necessarily believe plexiglass is needed. If the NHL wants to have aid in video review, the new "verification goal line" should be enough. Plus, won't we miss shots to the roof of the net only to have the water bottle pop up in the air? That is verification for a goal if there ever was one.
