The Toronto Maple Leafs had one of the best powerplay units last season, ranking seventh in the NHL with 24.0%, and it wasn't often you saw the Leafs with the man advantage and they didn't capitalize. However, a powerplay is two-fold, and having good defense on your blueline is crucial to keeping pressure, and the Maple Leafs only managed a 20.2 Net PP% (a more accurate measurement accounting for shorthanded and powerplay goals). It's not so impressive when you realize they gave up nine shorthanded goals with only 57 PP goals and something needed tweaking.
Craig Berube still has a lot of time left in the season to tinker with his powerplay, and bringing in Marc Savard was supposed to help elevate the Maple Leafs' powerplay but so far it's been dismal. If he wanted to give Toronto's powerplay a fighting chance, he should look to Ekman-Larsson to ensure they start finding that success.
