Not going to dignify the personal stuff with any comment other than telling you to grow up and act like an adult. You're suggesting taking away a key piece that allows the team to be competitive now. If the team is in the playoff picture, that's a horrible message to send to the group, which is why you don't usually see teams with a chance as sellers. Throwing in the towel just over a year after removing a locker room cancer like Green is not how a winning culture is developed. Pettersson's already on record stating that he wants the team to be competitive for his next contract.
All of this can easily be avoided by handling the situation one way or another before camp.
