I don't disagree with your take on JC at all and the players reactions to him. I feel like both can be true though: Toews lost the room, and Colliton never had really had it. We were all worried -- rightfully so -- about the team being receptive to him. The proof is in the pudding.
I remember the rumblings about the young guys being down on the vets, mainly Toews, in the room. There was supposedly a rift between Hartman, Schmaltz, etc. and the vet guys/Q. I feel like there still may be a residual effect from that situation, even though many of the young guys are gone and obviously Q is gone, which was the main part of the rift (Q's penchant for favoring/giving the benefit of doubt to vets but not the young guys, etc.). Pure speculation of course, but like you say, when I hear Toews speak -- even at the very beginning of the year -- the guy sounds utterly dejected.
agree to disagree, I reckon. I don't believe any of the vets have lost the room. I think the younger players absolutely listen and I feel like there is a fair amount of camaraderie between the players.
there is a reason the players you mentioned are no longer around. I am still waiting for the report as to what the hell happened in Florida in March 2017. after that trip, the team was never the same and we all saw what happened in the playoffs. there was a real rift then, but that has since been corrected.
I've said it before, but imo the thing that is never brought up as far as the compete level from all of the vets on a nightly basis is the fact that during the heyday, there wasn't a necessity to have everyone going balls out every night. Toews and Kane came up on a team with so many other good players that if they had a game or 3 without their best effort, it wasn't a big deal, others would step up. and then they would step up and others would have off nights. it allowed them all to stay fresh throughout the season, sure, but it also became a second nature. they could feel which players were feeling it on a given night and they played accordingly.
unfortunately, that method has continued since the 2015 Cup and with the roster being whittled down slowly but surely, it obviously doesn't work. but it is habit at this point, it is ingrained. I don't see it ever changing either because those guys know that it was successful and running themselves for 82 games straight will result in an empty tank come spring. sadly, the only way they make the playoffs in the spring is by doing just that....
edit: I would also add that I don't think any one player losing the room, be it Toews or Kane or any of the other vets, would cause this team to look the way they have. I think it has a lot more to do with the coach.
