Just for kicks I checked my online sportsbook and there are a bunch of props for this game and they're pretty interesting.
Pens +1.5 @ -200 (Pens unlikely to lose by 2 or more)
NYR -1.5 @ +170 (Rangers unlikely to win by 2 or more)
Pens +160 (Pens expected to lose)
NYR -185 (Rangers big favorites to win)
Pens -1.5 @ +500 (if the Pens win it'll be by 1 goal)
NYR +1.5 @ -650
To give you an idea of this:
Pens by 2 @ +850, by 3 @ +1200, by 4 @ +2000 etc.
NYR by 2 @ +450, by 3 @ +450, by 4 @ +600
ie Rangers unlikely to win by more than 1 but it wouldn't be surprising.
First team to reach 3 goals: Pens +180, NYR @ -110, Neither @ +250
Believe it or not that means the Rangers are even money to score 3 or more despite having done so once in the last 4 games.
Here are the odds of some players to score the 1st goal
Sid +765
Nash +855
Malkin/Honqvist +990/+1170
MSL/Kreider +1260/+1350
Kunitz/Perron/Comeau +1350/+1350/+1440
Step/Brass/Hags/Zuc +1440/1440/+1530/+1530
Bunch of other players (incl Hayes and McD)
...
Field +250
I guess that means Glass scores the 1st goal?
There's also individual player props on scoring a goal. I may bet on Zucc scoring @ +309.
