First, I apologize if (a) this is common knowledge; or (b) someone else has already done this. I'm pretty new to hockey stats, though I've been a fan of the game for a long time. I searched, but didn't find something similar. It seems to me that short-handed goals ought to count as far as a team's special-teams performance. A great PP isn't so great if you give up a lot of SHG, and a great PK can be even better if you score a lot of SHG. So, as of 2/23/19, here are the top teams in the league for special teams offense, calculated as (PP goals - SHG allowed) / PP minutes: 1Tampa28.8%2SJ23.0%3Winnepeg22.6%4Boston20.9%5Florida20.9%6NYR20.1%7Calgary20.1%8Minny20.0%9Chicago19.8%10Colorado19.7% And here are the top teams in the league for special teams defense, calculated as (PP goals allowed - SHG scored) / SH minutes: 1Arizona92.7%2Tampa88.4%3NJ87.7%4SJ87.1%5Vegas87.0%6Columbus86.8%7Calgary86.6%8Pittsburgh86.0%9Nashville84.5%10Winnepeg84.4% Two thoughts: (1) dang, Tampa Bay's PP is really lights-out, way better than anyone else in the league. (2) dang, Arizona's PK is just as good as Tampa's PP. Finally, here's an attempt to calculate the average goals/game due to special teams. It's calculated as (PPG + SHG - PPGA - SHGA) / G: 1Tampa0.582SJ0.313Calgary0.284Arizona0.255Winnepeg0.216Florida0.207Boston0.138Vegas0.109NJ0.0810Pittsburgh0.0711Minny0.0612Dallas0.0313Colorado0.0314Columbus0.0215Toronto0.0216NYI0.00 Any team not on this list is a net negative for special teams--they're giving up more goals in special-teams situations than they're scoring. Again, quick reaction: (a) Tampa is nearly twice as good as the next positive team, San Jose; (b) Toronto is essentially special-teams neutral, which surprises me; (c) Arizona may not have a great PP%, but their special teams contribute a lot to their offense.
