It may be over. It may have been over after Period 2 on Friday when the Rangers allowed the Penguins to score two late goals to cut the lead to one. It may have ended when Matrin Straka's apparant goal was disallowed. However, if and when it ended will not be revealed until this series ends. The Rangers are not dead yet, though they may be on life support.
Game 3 is a do-or-die game. Game 4 is too. Even of the Rangers win those two contests at MSG, Game 5 is as close to a deciding game as you can get. But the Rangers are used to these playoff situations, having faced the exact same situation last postseason. The Rangers are facing the favorite to win the Eastern Conference again. They fell behind 2-0 in the series again. And they have a huge hole to dig out of again. Last year, the Rangers climbed to 7.7 inches of the top, before free falling into oblivion. This time, however, the Rangers have the executioner on their side. They have the Mr. Clutch who can pull the Rangers out of the hole instead of pushing them back in.
So it is not over. The Rangers have a fighting chance, but will need to fight hard to seize it. They cannot give up 5 goals. They cannot score 0 goals. They must play the confident, winning style that shut down the Devils. They must get that late goal or that huge save to win. They must take no penalties, make no errors, and score on every shot. The margin of error is gone, but the window of opportunity is not. The elevator door is closing and the Rangers are not in it. Someone needs to step up. Someone needs to hold the door open. Or else remain on this floor. The floor of failure.
