Wow, after seeing your team I'm wondering if you're worried about this year or not. Good to have youth, but some of these guys are 3 years away from being studs, if they make it.

So, how many can you keep? I'd package the ones you feel less attached to and see what you can get to maybe finish somewhere in the money this year.

A few of them are kind of equal IMO so throwing a bunch out there might be an idea.

If I'm you (and I'm not, but what the hell, I'd keep:

J. Staal, Pavelski, Huberdeau, Wheeler, Voracek for forwards,
OEL, Edler, and Larsson for D,
and actually keep both your G.
As for your utilities maybe keep one D that you really like.

Throw the rest out there and see if you can get 2 star vets for your remaining forward and D slot, and a few others to help you be competitive this year.
