Hasn't Chris Ilitch slowly been taken over for his old man? Wouldn't you think that the ownership of the Wings, Tigers and Little Caesars would be handed down to him and the rest of their children? I doubt Mike or Marian want any of it to leave the family name.
It seems that way in some ways, but I don't really know that for certain. It's hard to imagine Mike letting them go as long as he has a say in things though.
