Which again proves that the usual "When Geno scores more points than Sid, it's because he faces 2nd liners" is just a bull****e argument, especially considering Geno has proved during an entire season that his stats were even better when playing at 1st line and so always facing teams's top lines than when playing at 2nd line.
Coming back to the subject of this thread, while i think Sid and his line has not been at his best in this serie, this +/- stat is blown out of proportion and very misleading in many ways.
Well yes and no.
Sid sometimes gets the 1st line match-ups and thrives and Geno sometimes gets the 1st line match-ups and thrives.
The benefit is to the Penguins though, every team doesn't have 2 shut down units for those 2 lines, so you have to pick one, if you put your effort to stop Geno, you run the risk of Sid and his line destroying you and vice versa.
In this round, it was Geno's line that thrived against the extra attention, Malkin is a monster like that.
