It's only terrible asset management if you are certain Kulak is more than a #6 and you're worried about resigning Valimaki post ELC.
If you can show me proof of either event occurring then your argument has merit. Otherwise you're just putting too much stock into the potential value of a tweener AHL defenseman.
This!
Yep, this is simply how it is. It is plain horrible management in general if you play a worse player over the better player. Whatever their contract or age is, you just don't do it. If they are clearly very even as players, then I can see the point. But if there is a difference between the quality of the players, you just simply ALWAYS play the better player.
Honestly though I can't compare Kulak and Välimäki, as I have not really seen Kulak play much. Välimäki has impressed me pretty much, but I have seen him play so far only against players of his own age, so it is pretty difficult to say how well he could do against adult men already. He does seem quite developed physically though, and even quite mature mentally for his age, so who knows, maybe he could even be pretty good in the NHL? But the key is still also of course what is Kulak's quality in the NHL? Seems that at least people here have pretty differing opinions about him.
