I bet he'd feel a lot better about his own development and skills if he'd have spent a couple months in Roch, working his ass off to get better and get back, and was rewarded with April NHL games, to build off of as a springboard, than he does after sinking with no lifeline for months and months, ending with demotion.
Even if he "shouldn't," he's a human, and this objectively sucks for any hockey player.
I'm not saying this will damage him or anything, or that it'd be anyone else's fault but his own if it did, but this kind of thing has a track record of damaging prospects.
