Seattle has one of the most stable fan bases in sports. As an example, I think Seattle would trade him for 1.1 this year for Murray but think the Cards would not do that given the QB's are similar in style.
That would suggest he is an asset that can be traded. No doubt it could hurt them but that is not known and could be argued downstream only based on what Wilson and the Seahawks do in the future.
Similar to the Raiders. Hard to say if the Mack trade was a win/win, win/lose, or Lose/win situation. That will take years to determine.
Seattle sure doesn't seem the type of team that is scared to the pull the trigger on any type of deal.
Wilson wants his money again; just a year early so moving him wouldn't be surprising. Of course after Odell being moved nothing would be surprising..... well, Brady being traded would be.
