If we get Simmons, I think you play him at the 4 and you surround him with young guys who can shoot, and keep anybody who dominates the ball on the bench. The idea would be to gradually upgrade the talent around him by finding guys who combine shooting with athleticism and defensive ability. First things first, though, you space the floor around him and let him work in space.
Really, the talent we've got on the team right now doesn't fit that blueprint very well. But if you get the superstar prospect, it doesn't matter who is already on the team. They could sell off everybody currently on the roster and just re-tool to fit BS's skillset.
