So you don't want Hyman on the first unit power play, you would place Puljujarvi above him? Say goodbye to Puljujarvi.
If the player has earned the time on first pp, you go with the better option that will lead to success and wins.
Even if he is not on first pp and still blows the doors out of the water with his play and prices himself out of the team. It is only a good thing because his value will be that much higher to get a good value return for him.
It's bound to happen, every team has to makes these type of decisions. Having an excess of good to great players is a good thing, you keep the best for your core and as tough as it is to let go of potential great players, it's also an opportunity to get a return that will solidify a weaker position on the team and maybe high draft picks that will come on cheap elc in the future.
My mindset is give every player on the team the opportunity excel and succeed. Let management deal with everything else in the offseason.
