Honestly, he's been spotting up and cutting off the ball more. POP is putting the ball more and more in Anderson's hands and Patty (for better or worse with Patty), but he's not as ball dominant as he used to be.
Manu is now more opportunistic which has spared his strength and legs. We are seeing more set 3 pt shots for him out of kick outs (Kawhi has set him up for a lot of open 3 pt shots when he plays with the bench), and we are seeing Anderson finding him cutting more instead of drives. They look for each other too. Instead of any of these guys doing it by themselves.
I actually agree with you having Anderson out there helps Manu out. When they have been with just another 3 pt shooter in Danny or Martin they don't get the same quality looks and they struggle to score as a unit. Of course bc of the abundance of Anderson critics around here, he doesn't get credited for making teammates better.
The Anderson/Manu bench duo is more dynamic than Martin/Manu or Danny/Manu.
Many of Manu's bad passes were overaggressive attempts to get the ball into the paint. POP mixing so many guys in (Boban, Martin, Miller, Simmons) with the bench was maybe a necessity in case you need those guys but it also made for many Manu errant passes to those guys. I don't want to jinx them, but Manu with Anderson has not been TO the ball that much and his assists have gone down as Anderson's have been ing. Only player fans will be upset about that.
I have also noticed Pop has kept Manu's minutes at around 20. I think that is ideal. Maybe in a close playoff game you increase that a bit, but not by a lot.
