A player like Vladimir Tarasenko would've been extremely useful to the Oilers. It would have created a lot of depth in their lineup.
However, as you probably know, he signed with the Ottawa Senators.
It was reported that the Oilers' bad contracts have prevented them from getting him.
Let's be frank, Nurse's and Campbell's contracts are too expensive for the performances they offer. This kind of management truly hurts the Oilers in the long run.
