I don't know how long Neal is going to be out, but if he's good to go tomorrow, I'd start Ginobili at SG and slide Green to SF. If Neal can't go, Ginobili should still enter quicker than usual, because whether Chandler plays or not, the Nuggets are loaded with big wings who are offensive threats, so a Ginobili-De Colo backup wing combination is not going to get it done.
You look at the upcoming schedule in general and it's going to be difficult to get away with playing Ginobili at SF much. They play a lot of teams with big SF's, who are offensive threats. They can hide him on a Barnes here and a McGuire there, but that's about it.
