My brain would be like a bigger swap. Signing Forsberg, trading Nylander (get Muzzin replacement that is young/controlled) and Muzzin (get picks/futures - can use those futures for whatever we need come deadline).
Or just keep Nylander, who will do Forsberg things for 2 million dollars less, clear cap space (Muzz, Mrazek, Kerfoot) and go get that Muzz replacement without trading Willy (We have more than enough kids and picks to move. Sandin + Robertson/Knies + 1st gets you into the discussion on any defender in the league likely to be available).
I'm not 100% against trading Willy, but replacing Willy with a guy who is basically 65 games of Willy but for more money, strikes me as a bad idea. I don't want us making moves with names attached just for the sake of making moves. I buy the argument that Nylander has been 90% of the guy we wish he would be and that we're running out of runway on his "cheap" deal and I would pardon anyone who was skeptical about re-upping 28 yr old Willy for 8/72 two summers from now. But we would absolutely need to replace him, and preferably for similar money or less.
