I personally prefer the Giroux, Backstrom and Nash side.
I wouldn't hesitate to make this move.
Is it a straight points league?
If PIM is a cat then yo might lose some value in that cat but I really really like this deal.
Backstrom >> Staal
Nash = Heatley (wash unless goals are heavily rewarded, edge for age goes to Nash)
Giroux = Burrows
I dont like that Burrows is dependent on his linemates. Giiroux has a higher upside and can create his own points. SOLD
