Hot take: the playmaking center shouldn't be high on the priority list
Sure, its something we lack, but how many of our problems is it solving? The whole point of a playmaker is to facilitate goals. If we drop Peterka for a set-up man, we're maybe re-allocating goals, but not scoring more. Not to mention, some of our scorers like JJ, tuch, and tage, are actually good at setting up goals as well. They aren't olofsson type of scorers.
This team was 3rd in the league in scoring rate at 5v5. We usually don't lack scoring, and when we do, its not because the offense is stalling after entering the zone, its because they can't get there.
So, if we still want to improve our offense what we really need are possession drivers.
When the offense is stalling its because we're not getting shots, and presumably aren't even in the offensive zone. Whether its forwards or defensemen that can transition the puck (notice how much we suck without Dahlin and Power), or forwards that can retrieve pucks and maintain possession after dump-ins (notice how much we don't suck with benson), we need those possession drivers.
As much as I'd rather have Rossi to Quinn at the draft, or would have traded cozens for him, I don't think he or EP really address the questions that need to be answered, particularly at whatever it would cost
