Big picture, this lineup has better defense and goaltending than the 19-20 leafs, more grit and skill in the bottom six forwards. The question is whether, when they get a full year playing with Matthews or Tavares, either of Mikheyev or Kassian can can produce the 50-60 points that Nylander is capable of. I'm guessing no, but they each get 40. With better defense and goaltending, that keeps the Leafs right where they are, in the standings.
Take LIljegren out of the Devils trade, at least. They'd probably give you Zacha and Severson for just Nylander. Could throw in more salary if you wanted. They have McLeod ready to try out at 3C, and have too much cash committed to a defense with too much offense and not enough defense, as is. Nylander gives them hope for the future and a roster spot to sign a UFA defensive defenseman, or develop one of the ones they have.
