Also another interesting thing I got from the Locke podcast on this: It seems like Quin is potentially tired of the criticism/blame he got this year. I think Quin really defended his players, but the reality is he might be tired of dealing with the Rudy/Mitchell thing.
My overall takeaway from Locke (and admittedly this might be me putting my personal opinion into this): Quin hated the way the Jazz played this year (this was explicit). He's tired of it, but since Mitchell has so much power he cant really do much with how many people are in Don's ear. The new FO/Ownership is all about keeping Donovan happy, so it's furthering the stress on Quin. Add to that the fans are turning on Quin and blaming him for this type of style that has led to the losses, furthering his frustrations.
Having expectations is difficult. You actually have to perform. When you're a tanking or up and coming team, there's no pressure to win and it's easy on everyone. Everyone is happier on a no expectations team, and I think SAS would be a good destination for him. He would definitely help them.
