Why the Mavs are Potentially Much Better Already...

I have speculated that he is at more risk of getting hurt going to the basket than popping, and he might be worried about it, consciously or not. 

I don't know if KP rolling will turn out to be a mainstay of the offense, but I will be surprised if they don't at least give it a try. Hope it works out!

If it would be only KP, then I would consider health as likely cause. But Mavs also stopped all Kleber PnR - Kleber was great with Luka in first two seasons. So I think the reason is something else and I have no idea what.
