I am playing in a 14 team dynasty keeper league with 10 minor spots

Offer:

I get Berglund and Dougthy for Ladd, Nicklas Jensen, Ryan Johansen and Chris Stewart


I know i´d give up a lot, but right now my team is stacked and i need to make space, because i have 4 first round picks for the upcoming draft.

my roster:

C - Getzlaf, Nugent-Hopkins, Johansen, Johansson, Stepan
LW - Ennis, Perron, Filppula, Lupul, Jokinen, Ladd
RW - Brunner, Okposo, Wheeler, Selanne, Setoguchi, C. Stewart
D - Bogosian, Carlson, OEL, Fowler, Sbisa, Whitney
G - Smith, Gustavsson
