It's not by design that we want to deploy soft lines. But non high picks, later rounds or trades where you're taking on young talent that 'busted' elsewhere - you need to go for skill. Try to take the guy who can break things open with skill, and hope he plays the right way or can learn. I'm sure the Hawks prefer a Toews or Dach like player (Dach alone is proof they take the tough playing player if given the chance) but later rounds there is no luxury. In the rebuild/retool you won't take the grinders, but the ones who can win games for you.
I mean they're constantly pushing Cat and Strome to 'learn the right habits' and 'play the right way'. I agree we are soft now, we definitely need more toughness and it's possible it only comes through trading our softer core guys - but if we end up as the Minnesota Wild, that's even worse.
So it's really not be design saying that is a little unfair, especially since Stan has built cup winning rosters before. We are in the stage of trying to get high level talent, the Kucherovs if you will, and then we can iron out the correct supporting pieces.
With all that said I share your concern that our current core pieces are too soft to compensate for. They either need to improve or imo we should think of changing out some pieces, and it obviously won't be Kane.
