The one Capital fan clown posted how great Ovie is and how his .98 PPG in the postseason ranks fourth since he entered the league for active players. However, since '11-12 his PPG is .70 while Geno has over a point per game and Crosby is nearly that in that timeframe. He hasn't taken his game to the next level in the playoffs in a while.
OV is now a player that requires another player to do something
first in order for him to be effective. It's not that he's not trying; it's that more needs to go right in order for him to show up on a scoresheet. He doesn't need that many clean looks to beat a goaltender, but
getting clean looks is a chore and beyond his control in a lot of ways. There's more variables involved in a sequence where OV scores than one where Kessel does.
And with as tightly as the Pens are checking him, he really doesn't have the space to get clean shots off. Every time the puck goes to him, someone just steps right into the space dead center in front of his body. Can't shoot like that. 8 years ago, his acceleration prevented this type of aggressive gapping, but that acceleration isn't there anymore, and hasn't been for a while.
Basically, he's a linebacker Brett Hull now, instead of a power forward Pavel Bure. The player he is now is still pretty effective, but he's a lot easier to mark than he used to be--and that's an athleticism thing, not a desire thing.
