When Russel landed on GSW it was a good fit to them since he actually give a extra fire power to the them and they should keep them since he can contribute outside and inside but he need to work with his defense since he's been outpowered by other players in the court.
That's probably their weakness, unlike Durant who can really make some good defense and have a good rebounding skills and blocking skills as well.
When Both Curry and Thompson will again healthy and these 3 will play in the court, its' gonna be Curry and Him who will be attack by their opponent since they do lack some defense.
Maybe they consider Wiggins but for sure it will not come since they know DLo is more valuable to keep and the one they really need is a true center which can held on their defensive side.
For me, I would choose Wiggins over DLO due to the fact that Wiggins plays good defense and he is also a legit scorer if given an opportunity.
