I talked about this in earlier threads but, Davion is heading into the last season of his rookie deal. I think he likely was always on the way out. You just couldn't justify giving him a 4/40 type deal, if he had a strong season.
The guard rotation is going to be Fox/Keon/Monk/Carter. 2 elite shot creators and 2 absolute defensive disruptors. Davion, Huerter are going to be gone.
