Buffalo isn't negotiating from a position of power on Eichel after his public statements regarding his neck injury. He may not have said he is done with Buffalo, but every GM in the league knows that is precisely what his statements regarding the organization mean.
Personally, I think the Wild should stay away from Buffalo as that organization just seems tainted right now. Also, their past trading experiences with Buffalo have been pretty crummy...was not a Pomminville or Stafford fan.
