Haha... well... I guess Malkin has been the closest thing on this team to an enforcer for a while. But that's just because the rest of the roster is uh... well... Therrien had a term for it, I think.
The team had Godard, Engelland, Asham and Rupp and Geno still stuck up for himself because he's a fiesty dude who grew up in one of Russia's steel towns.
It doesn't matter whether the Pens employ guys like that or not. Geno's gonna hit back almost every time, for better or worse.
And Sid will take a mental note and get the dude back when he least expects it if someone takes liberties. That's just how those two dudes are, and most superstars for that matter.
-edit- As stoked as I am with how much more physical, and proactive in that regard, the Penguins were in game 1. I think the Pens are missing a Ruutu-esque shit disturber. Someone who isn't gonna deter cheapshots (because that's not a thing anyone does, including Reaves), or someone that's gonna act like a mutual assured destruction guy who is gonna elbow the opposition's star in the temple. I want a dude who is gonna keep the other team losing their shit all night long and rattled because he's skating around being a little shit. Sorta what Hornqvist did to opposing goalies/blueliners around the crease--but I'm not sure that sorta thing fits with Sully's "shut your mouth, do your job" style.
