That is neither big nor long. Atlanta is up for sale. They don't even have a GM (IINM, Ferry was suspended). Quality of life can also be where you built friendships over the course of 7 years. It can be where your brother plays, where you have ties to several coaches, including the one who worked with you closely the previous season. I'm not saying it's likely, just that it's possible. There are many factors that might lure Paul to Utah. And many that would keep him with the Hawks.
Well as you say nothing is impossible, but with the turn the situation is taking in Atlanta, I would be very surprised if he left.
