Back in December, I called for the New York Islanders to abandon their two-goalie system. My argument essentially stated that abandoning the system would allow for one goalie to get hot and the other to be well-rested and ready to slot in when needed. Furthermore, it stated that a perfect two-goalie system had not been employed by any Stanley Cup-winning team in the past decade.
At the time, the argument seemed absurd to some (check the comments section of the article) and unlikely to happen, as both Semyon Varlamov and Thomas Greiss were playing well.
