That guy who replied having formerly minor-pro pretty much nailed it. Even back in the day when stand-up was the vogue, an awful lot of teams had trouble finding netminders with the training & skillsets, ability to play it and through no fault of their own; Coaching & training back in the 60's & 70's was often sporadic or just plain unavailable, could be expensive when you found it (summer Camps for eg) and out of reach for many. Some strange hybrids going far by simply being at the right place at the right time who technically were disasters. But, as the game then had as much to do with fists as skill and tended to be higher-scoring affairs, survived, actually thrived. Guys like the character Denis Lemieux, the psychopathic goalie from Slapshot fairly common actually.
