It's because of the Warriors floor spacing. Yes Curry is a great finisher, but watch the Warriors play, especially when they go to their Curry, Thompson, Green, Barnes, Iguodala line up. There is no help. You put Curry on a team that doesn't have the floor spacing that the Warriors do and his FG% in the paint would go down. This is also why I don't think he's better than some of the greats to play the game. Is Curry up there yes, but you give MJ or Shaq the same kind of floor spacing, guys who literally can't be stopped one-on-one, and their already impressive numbers would increase. Lets say we switch Klay Thompson with Jimmy Butler and Draymond Green with Blake Griffin (guys who are good but can't space the floor as well) the efficiency of the Warriors offense (and Curry) would decrease. The importance of floor spacing has long been overlooked.
