When NY Rangers Have a Power Play
The Rangers attempt 3.60 shots per two minutes on the power play, fourth best in the NHL behind only San Jose, Pittsburgh and Washington.
Of those that reach the net, their power play out-shoots Philadelphia's by a narrow margin of 1.88 to 1.85 (per two minutes), but the Flyers score on 12.8 percent of those relative to 11.2 for New York.
The Rangers are consequently league average, with 6.34 goals per 60 minutes and a power-play percentage of 18.2 percent.
As for the Flyers, they allow just 2.81 attempted shots per two minutes, lowest in the NHL. Their overall 84.8 penalty-killing percentage ranks seventh.
When Philadelphia Has a Power Play
Philadelphia's power play is top 10 by any measurement.
The Flyers scored 7.13 goals per 60 minutes, sixth highest in the NHL. Their 19.7 power-play percentage is eighth best, but mere decimal points from fourth.
In terms of shot-based data, the Flyers manage 3.48 attempted shots per two minutes, eighth best, but the Rangers allow 3.04, eighth fewest.
The Rangers have an .896 save percentage on the penalty kill, fourth best in the NHL, and consequently posted a fourth-best goals-against average of 5.32, barely beating out Philadelphia's 5.37.
Combined with their great discipline, the Rangers have allowed fewer power-play goals than any team except San Jose, and their 85.3 penalty-killing percentage ranks third.
The other notable factor here is the high potential for some shorthanded goals. The Flyers allowed 11 of them this year, behind only Toronto and Edmonton, while New York has scored 10 shorthanders, fewer than only Calgary and Carolina.
This one is almost too close to call. Both teams have effective power plays and penalty kills that should be evenly matched against one another.
In such a debatable situation, the tie could very well be broken by New York's greater threat of scoring a shorthanded goal.
