Similar to the baseball designated hitter, we should add a designated shooter. I'm thinking an additional player on the ice sitting at the top of the left circle who isn't allowed to move but is free to take shots on behalf of other players if they can get him the puck. We could try the rule for, say, maybe the next 5 years and see how it goes. This would allow both teams to ice 6 skaters and a goalie without increasing crowding too much, and increase number of goals by having high end shooters take more shots. Those are the only two reasons I have for this setup.
