I would assume not.
Your deal likely has Edmonton adding at least 5 mil in Murray, probably 3 in McCann, another 3.25 in worthless cap dump in Johnson, retaining 750K on Neal when we retained 750K on Lucic to get him, without adding much of anything of consequence that's guaranteed to be impactful - since we don't know what we're getting out of Murray anyway AND we're weakening our defence.
Could Murray bounce back - sure, but Koskinen is good enough right now. We need someone better than Smith to platoon with him but I wouldn't bet the acquisition cost or the probable salary that Murray is that guy.
We could just buy Neal out if we were that desperate to get rid of him and we wouldnt have to add Johnson to do it.
