Each team has a 23-man roster, of which 20 dress for each game.
Players can also go on and off the ice while play is in progress.
Goaltender Unlike his teammates, the goalie does not skate around the ice. His job is to keep the puck out of his net by stopping shots that can exceed 100 mph. The goalie can use any part of the body or any piece of equipment to stop the puck. The right and left defensemen play a dual role. They have to stop incoming opponents, preventing them from shooting at their goaltender.
