Not convinced of this or that its a fair comparison. Janmark is a career NHL vet with tons of experience to draw on. Yes, value in that yes.
Kostin is a player that has not had enough GP to scratch the surface of all he can be and one could easily say has much more potential.
In the win now philosophy I can see people saying keep Janmark but the Oilers are getting to be a pretty old team. Kostins energy and vitality and physical play could be helpful at present.
In anycase the club could have kept both and got rid of Foegele. Thats the right answer.
Canada cooler was better
