I wonder if Kraft can simply take his GM power away any time from a contractual standpoint.
Maybe the sticking point here is that Kraft can do this, but Bill would prefer not to but can’t control it. So he’s open to working elsewhere where they’d give him GM powers, but not just any old place. So this maneuvering says “We are open to keeping Bill in a reduced role, but if you might want him, feel free to give us a call.” Other teams might call with offers for him with GM powers included that he could consider and that Kraft could also weigh the value of the compensation and then they could ultimately decide as a pair which one to go with after a few days.
Or, possibly he simply just doesn’t want to leave and will do whatever Kraft wants. Hard to say.
