So, if I am the Rangers I pretty much just play the game, yet if someone comes in for a hit, maybe the Messier elbow comes up. If someone is near the boards, maybe they get hit harder than normally. They should actually finish their checks, which is basically a euphemism for hitting the player once the puck is already gone. Race for the puck, maybe the other guys gets tangles up in your skates or on the stick. If it come down to it, defense needs to come in without worrying about where the face-off may be, 3rd man in and such need not be worried about. Basically do the stuff other teams do all the time. Rangers are terrible at playing on the edge between what the league considers legal hockey plays and illegal plays, they need to practice that.
