The power play has been the story for the Edmonton Oilers and Toronto Maple Leafs so far this season, setting up a potential special-teams battle when the Oilers visit the Leafs on Wednesday.

After leading the NHL in both power-play goals and power-play percentage last season, the Oilers are only 2-for-18 with the extra attacker through four games. With two short-handed goals allowed, Edmonton's opponents have actually had an equal amount of success during the Oilers' power-play chances.

Coming off consecutive home losses to the Montreal Canadiens, the Oilers allowed Montreal two power-play goals and two short-handed goals while going 0-for-10 on their own power plays.
