Their starting lineup will probably be something like Mudiay, Nelson, Gallinari, Faried, and Nurkic, with Chandler, Harris, Papa, and Jokic.
If Nelson struggles with his outside shot again next year, that team will not be able to space the defense at all, even with Gallinari.
I think the reason why they resigned Chandler is because they plan to trade Faried and start Chandler and Gallinari at the 3 and 4.
