So basically Getzlaf for Ghost. I'd say do it for sure.
Giroux/Tavares/Getzlaf/Panarin/Couture
Ekblad/Doughty
Holtby
Im not sure I trust Mrazek enough to be a keeper over Couture. Make a strength and work on your weaknesses for next year.
EDIT: Drop Stempniak
Getzlaf and Hoffman
for
Ghost and Stempniak. YUP.
