The Montreal Canadiens have turned this Eastern Conference Final into a real series now with their Game 3 win at Madison Square Garden on Thursday.
The New York Rangers had an opportunity to effectively end the series with a win in Game 3, but Sunday night's Game 4 now sets up as a critical contest for both teams.
The Rangers would love to head to Montreal with a 3-1 lead in games. The Canadiens want to turn this into at least a six-game affair that sees them make a difficult comeback at completion.
Let's take a look at the keys for each team as they prepare the Game 4 battle in Gotham.
