What they want to do will not be accomplished this season when it comes to style of play.
Bron is doing way too much. If he would just play as a 3 man, like Leonard do in SA then he was be better off, but he has to do everything which is the demise of his previous Cavs teams before the Heat. Bron never mastered one position. He is just good at all. And better than most people that comes to his team. That's what makes GS and SA good teams. All their pieces consist of players who play only one position, so you don't have to expect them to do more than they are asked.
You're usually spot on but GS actually has players that can play more than one position and that's part of what makes them so dangerous and good. Green can play the 3-5, when they go to their small ball lineup he's a 5. Barnes can play 3-4, Iggy can play 3-4, Speights can play 4-5, Curry can play 1-2.
