One would think the 3 best fits for the RW spot with Kreider and Z are Vatrano, Tarasenko, or Buch (if he is available - which I am not sure he with another year left on his contract). All 3 have played with those guys before, which gives them an edge. The other talked about option is Eberle. Pretty strong chance one of those guys end up on the Rangers. Then I would target a solid physical stay at home dman, and away we go for a long run hopefully.
If you aren't going to take a big shot now with this team in 1st overall, I don't know when you do. The East is tough, but remember very high chance/almost for sure Florida, Toronto, and Boston end up 1/2/3 in the Atlantic in some order, which means we can only play one of those teams, and it wouldn't be until the ECF. And Carolina we wouldn't play until round 2 if we play them, since we'll finish 1/2 in the Met in either order. That is a good setup for us.
