Personally, I am not so sure that Edmonton would be a destination of choice for Erik.
The reason I say this is simply that I don't consider the Oilers as being on track for success by default. It's not like they pay their time in purgatory and then heaven awaits. It doesn't work that way. They could conceivably be no closer to Stanley Cup territory than the Arizona Coyotes.
If he wants to play in a hockey-mad city and be part of a quest for success, maybe not a bad gamble. He certainly would increase the Oilers chances. The Oilers brass never quite got that you need something good on the D corps. Kevin Lowe, McTavish and company should all have been fired long ago, but that is another story.
