I'm sure that when everyone is back healthy it won't be that evident, but with the current injuries and roster of GSW this season I don't think that trading D'Lo will be the answer.
DLO in order for him to be effective, he needs to have a lot of attempt and that would limit the attempt of Curry and Thompson, so it could probably be a good solution to trade him and get a player that is physical, knows how to play good defense and are not afraid to attack the paint, they probably need someone like Iguadala, like a younger version of him.
