With Yandle @ 50% and John Moore going the other way I'd assume they are only taking on about 1-1.5M extra cap. I don't know the contract situations though.
They have St. Louis, Zuccarello,Stempniak as UFA this year, Stepan, Hagelin, J.T.Miller, Fast and Lindberg as RFA.
It's gonna be tough for them, I don't think they have space for any new player, but they can keep most of the guys on their team, especially if Zuccs raise will be just from 3,5M to 4,5M.
