The goaltender, or goaleur, as the French would say, are the backbone of the team, playing the angles to stop the puck from entering their net.
Since the 1990's and on, the goalies have received a lot of criticism for the amount of over-sized hockey equipment - the over-sized catcher's glove, pants, sweater that bags around the body to slow down the puck or stop it, and the pads that look to tall for the goalkeeper.
But this is a big improvement from the early years of NHL hockey. Years ago, the goalie had leather pads that would absorb water during the game, increasing the weight of the goalie pads by 50% by the end of the game. The catching gloves size was 50% smaller than it is today, the chest protector was cotton pads sewn together, many goalies were playing hurt or bruised taking shots to the body.
Goalies wore no masks before the 1960's either. Being a goalie required that you be brave and have nerves of steel.
Maybe not in the case of goalie Glenn Hall of the Detroit red Wings, Chicago Black Hawks and the St Louis Blues though. He was brave but his nerves were rattled at every single game, he was sick to his stomach, before the game, and even between periods. But most goalies just develop a quick reflex to keep the puck out.
Many years of training to play the position of back stopper for their team, facing slap shots traveling up to 95 mph, the job of being a goaltender is a demanding one.
