UPDATE: The Rangers have asked the NHL to clarify the infraction that led to the penalty shot, but have not asked the league to review Malkin's slew-foots (no suspension), all according to Rangers Report.
You take one part power play, two parts Jagr, and three parts Lundqvist. Mix them in a very large bowl shaped like a perfect circle, sprinkle in a healthy does of timely penalty killing, a pinch of gutty play by injured players and players replacing injured players, and a dash of frustration on the other side, and you have a recipe for winning that keeps the Rangers alive for one more game in their second round series -- not only keeps them alive, but gives them something to build on while sowing seeds of doubt in Pittsburgh to go along with those sprouts of frustration.
This was the Rangers' recipe for success even before losing Sean Avery and Blair Betts, along with some of Chris Drury's effectiveness, to injury -- we'd already gotten an article ready for the upcoming May issue of Blueshirt Bulletin that outlined just how important it was for the Rangers to have Jaromir Jagr and Henrik Lundqvist, their two most important players, carry them through the playoffs, with the power play chipping in the goals that win games. Against the Devils, it all clicked, even if the power play wasn't there for the first two games and Lundqvist had a couple of games he'd like to have back.
But against the Penguins, there was always something missing. The power play got a huge goal early in Game 1 with Lundqvist keeping the Rangers afloat, but everything went AWOL in blowing a 3-0 lead. Lundqvist sparkled in Game 2, but Jagr and the offense were blanked, with the power play denied the goal that would have sent the game into overtime by a quick whistle. In Game 3, Jagr was a beast, but Lundqvist could not make a game-saving stop and the power play was once again blanked and humiliated, as was the penalty killing for a third straight game. The Pens are to be credited for taking an essential ingredient or two out of the Ranger attack for all or part of those games.
But this time, it all came together for the Rangers. Lundqvist kept the Rangers in a scoreless tie through the first half of the game (31 minutes, actually) when the Pens outshot the Rangers 15-10, including a pair of stops on Evgeni Malkin that had him banging his stick in frustration. But as valiantly as he was playing, the depleted Rangers didn't appear as if they had what it took to score a goal, especially with Scott Gomez having an off game skating with Nigel Dawes and Ryan Callahan, Drury clearly hampered centering Brendan Shanahan and a dynamic Petr Prucha, and Martin Straka losing the handle every time he had a play on his stick (including a breakaway) despite having a good game otherwise.
Jagr took over at the exact moment one would think that it was going to be up to him to do it himself. Surely everyone at the Garden believed just that as he streaked up the left wing on a solo rush, cut to the middle, and whipped a whistler past Marc-Andre Fleury to break the scoreless tie. He lay on the ice for a long time afterwards, unable to celebrate his goal after being laid out with a hit to the head by Brooks Orpik -- he was lying there wishing he could do the celebration scene from "Jerry Maguire", he told reporters later. But he got back up and assisted on Brandon Dubinsky's goal early in the third period and scored the empty netter to seal the deal late in the game -- both of them power play goals, the special team finally coming through after an 0-for-15 streak of futility.
But it wouldn't have held up without Lundqvist's continued heroics. In addition to some flurries around his net and help from one crossbar, Lundqvist stopped a pair of breakaways and a penalty shot -- a shorthanded breakaway by Ryan Malone and one by Malkin that led to his penalty shot. He had help from his defense, with the Rangers outshootiing the Pens 21-8 between the middle of the second period and the last five minutes of the game -- Paul Mara had his best game as a Ranger, aided by some timely plays by Jason Strudwick, playing in place of the Chirstain Backman turn-it-over machine. But the saves on Malkin and Malone were huge, keeping the Pens from striking at the Rangers the way they had in the first three games even when the Rangers were outplaying them.
The penalty shot call was a mystery. Dan Girardi, chasing Malkin without a stick, pushed him lightly in the back with his hands. Somehow, Malkin's legs went out from under him feet-first, defying the laws of physics for a check from behind, but not the dynamics of diving. It was a check from behind, but that penalty is a major penalty designed for dangerous plays where a player can be injured, not the kind of light pushes from behind designed to separate a player from the puck that one sees all game long -- one would think that a major penalty, if warranted, would supersede a penalty shot. Curiously, even though he was not called for diving, an apparent goal was denied Malkin on the continuation of the play because he pushed Lundqvist into the net after the save was made -- but if he went into Lundqvist because of a penalty, it shouldn't have been considered a push. All in all, a series of calls and non-calls that were all wrong.
The game got ugly once the Penguins fell behind 2-0. Apparently believing it their birthright to win every game, to not get hit, and to not have any calls go against them, the Pens lost their cool, beginning with Sidney Crosby, who went after Girardi after a clean check to Marian Hossa, with Malkin, a sore loser after being sportsmanlike in victory, joining in. Both Penguin stars sat in the box together as the Rangers went on the power play, certainly not a recipe for success for Pittsburgh. Then, at the end of the game, as Jagr scored an empty netter, Malkin slew-footed Mara twice, the second time touching off a melee. Drury may have been slew-footed too. Malkin was not penalized for his acts, even after being the beneficiary of the phantom penalty shot call.
But one win does not negate the hole the Rangers are still in. They cannot lose a single game more in this series. Can they recreate their recipe for success again three times in a row, beginning Sunday afternoon in Pittsburgh? On the Rangers side of the ledger, Jagr and Lundqvist will have the biggest say, along with the special teams. The Penguins will have something to say about it too, but if their say is no more than the frustration they showed in losing this game, the Rangers will have a good chance to extend the series one game at a time, which is all they're looking for at this point.
