Terrible proposal. Way too much for Kovalchuk, and I like Kovalchuk.
It is a lot to give up for a player that is getting up there in age, and who's best seasons are behind him. Sure, I bet he is still effective right now, but I also bet that he is declining and every year will show that. He is also a flight-risk as well.
Besides, why would you want to stack the top line? If Kovalchuk came to Calgary, I would put him on Bennett's wing, as Bennett deserves better than playing with scrubs. That would balance the Flames scoring lines into 3 good lines. You don't see any other team really throwing their three best scorers on the top line any longer.
Hickey isn't an average prospect, and neither is Klimchuk either. I would bet that Hickey ends up making the NHL, and probably as a top 4 defender at that (elite skating, great first pass, and generally good at everything). Klimchuk just needs to stay healthy for a change, but he has such a wonderful snipe of a shot, and is also good in all 3 zones. Just needs to stay healthy.
It will be interesting to see where he goes and for how much, but I would be surprised if that package came close to this.
