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.
Indeed. Iggy types that will be fitted with the system. Though it's really hard for them find suitable player that will fill out the missing piece, lots of adjustment will be made once all the players will be there and healthy to play.
Curry and Thompson have the chemistry and whoever will be added to them will need to be willing to play according to how the system sets up it should be a role player that knows where to place himself inside.
