Why do you want Zetterberg so bad? Is he more than C eligible because if not you really don't need him.
I think you need to do a couple things here:
1. Get a better LW2 by trading one of your RW away (maybe Zetts is LW eligible and that's why you want him - I don't know)
2. Get a 4th Dman! You start 4 and yet you only have 3?
Lets assume that Zetterberg is LW eligible. You can approach this two ways.
1. Give him Giroux straight up - in a 1 year league you may have to pony up more
2. Give him Kipper+Okposo for Zetterberg+donkey G.
With you having to start 2 G every week, I would personally not trade away a G (especially Kipper who's hot)
BUT if you want Zetterberg that much, that's likely what it will cost you...
Another thing you can try is pawn off Bergeron+ for him...hope he bites on Bergeron's solid play.
