Leading my H2H league so far. Karlsson's owner is hovering around 8th or so, top 6 make the playoffs. I made an offer to him the other day of Yandle+ for Karlsson, pushing the fact Yandle could help him make a push for the playoffs, with Karlsson gone for the year. He declined, saying he would need to have one of my top guys like Giroux, Malkin or Ovie involved to consider it.

So, should I consider that, for the chance to get Karlsson? I usually end up keeping 5 F's, 2 G's, and 1 D-man each year (Yandle has been that D-man each of the last 3 years). Big upgrade if I could get Karlsson.

Out of my Big 3, I think Ovie is the only one I'd consider including in this (my, have poolie times changed in 3 years!). Should I think about structuring a deal around Ovie and Karlsson? If so, what should it look like, going either way with other pieces involved, or draft picks too? Should both Ovie and Yandle be involved? If not, any other ideas I could pursue? I'd appreciate any and all creative input!

My 8 Keepers in bold:

C: Giroux(C,RW), Plekanec, Tlusty(C,LW), Boyes(C,RW)
LW: Ovechkin(LW,RW), Benn(C,LW), Elias(C,LW)
RW: Malkin(C,RW), Seguin(C,RW), Gagner(C,RW), Voracek
D: Yandle, Campbell, Hedman, Schultz
G: Lundqvist, Crawford, Brodeur
