I don't think its fair to criticize monty williams' rotations last night. The Suns focus was clearly on fixing the defense and I thought they did a great job. They wanted to force Jokic to beat them. He shot pretty well, didn't get to the free throw line and only had 5 assists. I'd say their game plan succeeded. Murray and Porter didn't do anything and KCP didn't do much until things fell apart at the end.
If Ross or Warren had played I don't think their defense would've held up.
Their offense was really working well enough in the 3rd until Paul got hurt which I think is the reason they lost that game.
The Suns rotations focused on defense assuming that Booker, Ayton and Durant could carry the load on offense. Durant missed easy shots, Booker made some bad decisions in the first half and they stopped going to Ayton in the second half. If they fix those problems I think they have a solid game plan.
