McDavid and Drai play their entire powerplay, and then come right back out for their next regular 90 second shifts. That has gotta tire them out as the game wears on. The past few seasons it always feels like the Oilers are an unstoppable juggernaught the first ~30 minutes of every game, but then there is a gradual ebb of their energy and effort level as the game wears on. We just need to weather the early storm and keep the game tied, or within a goal, going into the 3rd to have a solid shot at winning every game.
