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.
That's their problem since they don't have a player who can contribute on the paint and it's good option for GSW to trade DLO while he's value is good but they should really look on the big mans who are great maybe I think the perfect fit for them is Capela,Drummond or maybe Tristan Thompson is a good fit for them since recently the cavs put him on the trade block so maybe it's best for the Dubs to grab that opportunity.
