It’s a topic I think most probably have an opinion on and are somewhat convinced they’re right. I’ve always been of the opinion that a great penalty kill is more important that a great power play. If you can score 5v5 then a great power play is a bonus. Whether you can score 5v5 or not, if you have a poor penalty kill it can bury your team.
We’ve seen teams in the not so distant past win a Stanley Cup with a bad power play. Until recently we haven’t really seen a team win with a bad penalty kill, at least in the last ten years.
