I would be very VERY surprised if Dwight stays in LA.
LA has yet to make any roster moves or get rid of D'Antoni, both of which are necessary if they want to make Dwight happy.
Not only has Dwight been very public about how much he dislikes playing in D'Antoni's system, but he has also said that his priority is to be on a winning team. The Lakers will not be a winning team next year, even with him. They will struggle to make the playoffs again, and might even miss them this time.
I think he is going to Houston. It makes sense from literally every perspective.
