After a quick check of NHL.com, Calgary's PP after 7 games is 5th in the league at 26.7%, only behind St. Louis (33.3%), Tampa Bay (32.5%), Edmonton (28.6%), and Ottawa (27.3%).
Unfortunately, their PK is 29th in the league at 69.6%, only better than Winnepeg (62.1%).
Very weird specialty teams stats. Hopefully that PK improves!
