I think there are a few ways outside of Newhook to ale it work, but it will hurt to make that trade.
They probably hurt even more though.
Realistically Newhook's top end potential here is that of a 2C. I think if we are looking to bring in a legit 2C, especially a youngish one it makes sense to use Newhook as the big bargaining chip at this point.
Especially considering if the play is Zibanejad or Hertl, we could easily re-sign either guy using Kadri's money.
I like the idea of trading for Hertl then signing him to a 6 year, ~42M sort of extension.
