If Montreal plays or should play the 1-1-3; all they would have to do is read plays effectively and know your role based on your position on the ice.
The dedication to the 1-1-3 is one of the reasons that they might not score off the forecheck as much as they probably should. Instead of being overaggressive with a second or third forward in support, the ideal is based on getting the puck back by intercepting the pass or controlling the dump in.
That is boring – incredibly boring, sometimes. But the puck stays out of the middle of the ice, and this strategy takes away the opponents’ ability to enter the zone with possession, which are two keys to success that might help.
