I would love to see Ward gone, and Wingels as 13th forward or gone (both for cap space to bring up some youngsters and to hopefully make a move).
If Goldobin can come up and play effectively on the RW of either the Couture or Hertl lines, that would be perfect. And as a playmaking RW he should fit with those goal-scorers.
I would then like to get a skilled young guy with at least a bit of experience to play with Hertl on the LW in the line-up below. Tatar maybe, or someone like him. Young, but with some experience, expiring contract but RFA, and even better if he might work well with Hertl (Tatar is Slovak while Hertl is Czech, but I would hope that at least speaks the others language).
But if that doesn't work out I wouldn't mind trying Karrlson as 3LW and trying Goodrow at 4RW before the TDL to see how things work. Since Goodrow has shown a bit more offense, has some NHL experience, and might supply that "toughness" that DeBoer seems to love in Haley. Or even possibly put O'Regan on that 4th line as RW/C with Tierney at either C or wing.
But I really want to see this team by 4 lines deep with some offensive skill on all 4 lines and not too many offensive black-holes or defensive trainwrecks.
So the lineup would look very roughly like this:
Marleau-Thornton-Pavelski
Labanc-Couture-Donskoi
(Tatar)??-Hertl-Goldobin
Boedker-Tierney-Karlsson / Goodrow / O'Regan
Wingels (possibly traded)
