I disagree. The reason we were successful last season as opposed to the prior seasons with stacked rosters is last season we leaned at times on "unproven" talent (Stephenson, Djoos, Vrana, even Kempny to an extent, etc.) This was a departure from seasons prior where we literally only buttered our bread with guys who had "proven" there worth (see the Schmidt debacle of 2016-17). Our "core" is aging, for us to be successful in the long run we need to give younger guys room to grow and make mistakes.
There were stretches in the past where a guy like Vrana was benched for even farting wrong meanwhile veterans had an unlimited leash. I think Reirden is looking at developing young talent, he knows you get nothing from benching a guy like Vrana, he needs to learn his lessons on the ice.
