I was watching the Sharks-Ducks game on Saturday and the Sharks announcers - I'm not going to lie, I don't think they know what they're talking about most of the time - said "San Jose has the third-best power-play in the league." Really? Let's look at 5-on-4 performance over the last four seasons:
Not only does San Jose have the best power-play in the league this season by a massive margin, they're way ahead of the next-best team we've seen since the NHL started tracking this stat in 2007-08. When you're trying to evaluate special teams performance, don't be misled by luck-driven PP shooting percentages like Vancouver's (Edmonton is 3rd in the league in 5v4 shooting percentage, after all) or teams that spent a lot of time at 5v3. The PP is all about directing shots on goal.
