Bourque isn’t a bad PK’er. He’s worse than Soda/Calvert/JTC but he’s next in the line after those ones based on what we have.
Realize the Avs active PK is a little unorthodox and not easy to learn too. You say you thought Greer handled his PK minutes well which is really odd considering he hasn’t played a second on the PK this season. AJ Greer has yet to step on the oven during a penalty kill in his NHL career so you’re seeing something else there.
Bourque is a much better PK option than Greer. Not because of Greer’s ability but because it’s complex and he likely doesn’t have it down yet. Bourque may not be the best PK’er but he’s one of the few that knows the setup.
No, actually he's horrible. He may be the worst possible guy to have out there. Even MacKinnon would be a better option, though no one in their right mind would ever use him in that capacity.
He isn't able to read or anticipate anything out there. Even fan-faves like Sheldon Dries are quite good at getting sticks in lanes to break up passes. All Gork knows how to do is block shots. And even then I don't think he's particularly "skilled" at it. He's just willing to do it. It's no coincidence that a lot of times the Avs' PK fails, Gork is out on the ice. Their ability to win back and clear the puck is severely compromised whenever he's out there because he is by far the least capable of reading the play and has by far the least amount of puck skill on the team.
I don't think the Avs' PK is that complex. They approach the guy with the puck in a wide arc to try and limit passing/shooting opportunities, and the forwards up front switch off depending on where the puck is. I don't think it's all that complicated. Personally I think it's way too passive and focuses far too much on shot blocking instead of a more aggressive approach that could lead to more turnovers and at the very least, less time spend in the defensive zone.
I really think "good at the penalty kill" gets thrown out there too often. It usually just means the guy is on the PK a lot, not that he's particularly good at it.
