Demko's workload ended up being totally ordinary. 60 start full-season pace. They iced Dries and an AHL blueline because they traded Horvat with no replacement and traded Schenn and shut down OEL.
The single biggest thing right now, by far and like not even close to anything else, is to have the team's three young superstar players (Hughes, Demko, Pettersson) happy and committed to this team long term. And all three clearly weren't and had voiced displeasure about the team's situation. And so, yeah, they I think tried to say 'you're our guys, you will have the opportunity here to get superstar icetime and level up to the game's elite players' and that's mostly what happened.
It actually kinds of hurts my head to see the level of performance we saw from Hughes/Pettersson over the past couple months and two guys looking like they're breaking out into absolute superstars ... but that's a bad thing because it drops us a couple picks in the draft? What on earth. Priorities are just so whacked with this fanbase right now.
Also once Horvat was traded and OEL shut down they simply didn't have the depth at C and LD to do anything other than play these guys lots and it isn't an effect that was unique to here - Anaheim was playing Cam Fowler 30 minutes/game down the stretch, too, because the other options were so poor.
