I think these days team roll with 3 lines that all can score with a 4th line that is a bit more energy. There is no shame on having a top 9 that looks like this:
Caufield, Suzuki, Slaf
Armia, Dach, Roy
Ehlers, Newhook, Anderson
Is it a top 9 that bring us close to a playoff spot, not sure I mean we had what 1 game with both Newhook and Dach healthy and very few with Newhook and Roy. To me this moves the needle in the direction of the playoff. Replace Armia with Ehlers if you prefer having him in your top 6 or if Ehlers is too expensive to get for just 1 year, go after Kakko! I would prefer that over paying a very steep price for Necas, Zegras or Perfetti
