It's not about the improvement, I just thought anytime he can be injured again as for me he is already fragile, sorry to say this, it's just my opinion.
Same with DRose, I'm afraid that when PG will be injured again, he would struggle to claim his status again.
Good thing now that he has learn to be more accurate shooting outside, that would take him away from driving into the basket and he just need to be more careful now as if 2nd injury will happen, he might not be able to recover well. Sorry again,...
Maybe one of the reasons why PG13 and Westbrook did not worth with the OKC is because while PG13 has improve his shooting, Westrbook also struggle with his shooting that very season.
