Klay Thompson's Defense

[Ghost of Podkolzin]

DJJ was elite-ish while Naji is "just good to ok-he-is-really-good". The Mavs took a step back with that one personnel move.
But collectively, the defense evens out.

While Green is a disruptor with a constant motor in him to hustle -- Grime's D is better.
THJ at his most focused form isn't a negative on D, but that rarely happens -- Klay is still better.

Any period where DJJ becomes unavailable due to injuries and the perimeter D comes crashing down. While Naji-Klay-Grimes wouldn't be anywhere near DJJ, two of three would most likely be available in any given play date.

I watch more NOP games, other than the Mavs.  I would say Naji is at least an even defender with DJJ.  Then you have Klay over THJ and Grimes over Green. Individual talent wise, we are superior to last team's roster.  Add to that that Kidd's a defensive savant, we are going to lock it down.
