The Oilers still have Nuge and Hyman to play on McDavid's wing. Nobody is sure if Kane is going to be back or not, but he was certainly good enough on the ice to warrant bringing back to play with Drai next year. Matt Savoie is probably going to get a good, long look as a top six winger this year as well,
They have to figure out how to dump their current underperforming wingers before we can move out defensemen to fill those gaps. The catch is, that we do need to move out salary, but its not on the blueline, because if we move out Walman, we have to find a replacement anyway.
