Dunno if guys like Kuhn, Rowney or Jooris are really capable of that either. We're just gonna have an underwhelming 4th line until JR can address it this summer.
Strangely enough, we could have a pretty skilled 4th line if certain players were called up and played ahead of certain useless ... ehem ... penalty kill specialists.
A bottom six of (or any mix and match winger combos)...
Sheary - Sheahan - Kessel
Simon - Brassard - Sprong
..certainly could provide the Pens with 4 lines of relentless offense they could roll out there.
