Not sure if I'd overcommit like that and make the error NSH did with the trade Johansen for Seth Jones, which, a couple years later, was probably not the answer for them at 1C.
I hadn't thought about Poehling though, and I believe Kotkaniemi will be our 1C in the future, he's creating so many quality chances already, he hasn't scored yet but we see promising things, and he's a complete player, so right now isn't the time to trade anyone, let the kids developp and when Poehling graduates we'll have a stacked center line, and even if it's not the generationnal Crosby / McDavid type of 1C that we have, we can still win with Patrice Bergerons and Anze Kopitars (actually I can see Kotkaniemi developping as a mix of both players).
