Pretty obvious answers. The team had flatlined, Hiller is what, 10-5-1 or something like that?
He got the veterans to perform. The injuries meant that a number of kids HAD to be dressed, but its obvious that they aren't trusted to play yet. Its a no-brainer that he would play JAD over Kaliyev given what they are trying to accomplish. JAD never actively hurt you the way Kaliyev does. Kaliyev's low effort forecheck and backcheck were key components in a goal against the other night. He doesn't have the track record of a veteran making those mistakes, and holding him accountable now might help him in the future. If he responds poorly to the challenge, well, that's on him. Not everybody makes it. We saw a player with an arguably better pedigree in Bjornfot get lost in the shuffle. Had they prioritized development, yes, of course they might have hit on more of their swings.
You can't blame Hiller for anything, he is getting results. And they are terrific results, even if the end goal is the longest of shots.
Its Blake's responsibility to comprise a roster, and he has chosen to chase something they cannot catch. We all KNOW this, but if you have a veteran heavy roster with misguided aspirations, that isn't on the coach to rectify. The path to nowhere started with Danault signing.
