I agree, I believe the extra cap space we have will be devoted to a trade for another defenseman, to me it's who will have to sit down when that is done.
We better trade one of our defensemen then in that deal, which would be more than awesome.
Foster sits in the meantime. He's really just bad defensively and it doesn't cover the slight help to the PP. Its been a good pick up for the past two weeks considering the injuries.. but there's no chance he keeps Larsson or Greene or Tallinder from the lineup.
