For Miami, I do like Winslow coming in, but if you're talking about sheer talent against talent, Cleveland has it over the rest of the East. They would be top 2 or 3 in the West, IMO.
Just watched some summer league, and Karl Towns looks like the real deal. His passing made him pretty dangerous. And with guys like Wiggins and LaVine cutting to the basket.... there should be no shortage of fireworks.
For the Lakers, D'Angelo Russell looked pretty damn smooth with the ball. He and Jordan Clarkson should make a great pair out there. Just takes time. Also liked how Julius Randle attacked the hoop facing up on Adrien Payne.
