Josh Anderson became a really effective penalty killer. I think Brendan Gallagher could be a good penalty killer, he's tenacious and wins puck battles, and getting it down. Jake Evans, he says he loves nothing more, aside from scoring goals, than icing the puck at Bell Centre and hearing the fans go crazy when they ice it.
Penalty killing, a lot of it is just being tenacious and just working hard with a good system set up for it. They had a good system set up for it last year, but 3 key guys are missing from it in Army (Joel Armia), Dvoarak, and David Savard. But I think they have enough guys there that they can plug in. As you mentioned, Josh Anderson wasn't a penalty killer with the Canadiens before last year but became a very good one.
