Lucky for him, the plan is to move a winger or two this summer.
Because Kaprizov is coming in and pushing either Fiala or Zucker down to the 3rd or 4th line. Or possibly both. They will need to at least trade two this summer if they want to have Kaprizov in the top 6.
There is as much potential for Donato to get top 9 or top 6 minutes as there is for Greenway.
Unless the Wild are going to roll 3 scoring lines (which would be interesting), I'd rather keep the traditional top 6 and then a checking line. Donato hasn't shown much in terms of playing defense to be a checking line winger. Greenway has shown to be a better top 9 winger than Donato, because he doesn't need to be sheltered.
There's a difference between being a better fit and being a better player. Considering your whole argument is that Greenway is a better fit, I would think you'd know that.
And Donato is a better fit, but that doesn't mean he isn't a better player than Greenway. As well, Greenway may be a better fit on the PK than PP.
Passable defense is all that's needed for a scoring left winger. I don't need Donato to play the PK, I need someone that can score.
And we'll have Kaprizov coming in for that, not to mention Parise, Zucker and Staal have all looked good this season and signed for another season. Not to mention Fiala has shown some flashes of offense. And fans are expecting big things for Kaprizov, so we'll need to move a winger or two to ensure Kaprizov gets the time in the top 6. So, unless you're assuming that Fiala is going to get demoted to the 3rd/4th line and we roll this:
Parise - Staal - Zuccs
Donato - Mittelstadt - Kaprizov
Fiala - Eriksson-Ek - Kunin
??? - Rask - Hartman
So, either Donato or Fiala are wasted on the 3rd line, unless they want to push Eriksson-Ek/Kunin to play more offense, which would be a waste of Ek's burgeoning talents.
