I never spoke definitively on claiming he can't be an elite scorer on a contender, just that I have some doubts.
I bought into him being an elite scorer in the first half of the Clippers series. He regressed over the next 3 games. I bought into him being an elite scorer a few times this season. And he's regressed again. Again, I can sit on here all night and post screen caps of Kawhi getting the ball in one-on-one isolation situations that are purposely created for him (just watch the movement of the offense and how they run to specific spots to create spacing for him), and he gives the ball up.
It's him parking himself as much as you think Pop is parking him. And I don't have a clue in why Kawhi just doesn't attack in those spots. A confidence thing? A wanting to play team ball thing? You soon forget that Pop needed to instruct him to be aggressive against Miami in the 2014 run, telling him to Tony, Tim, and Manu, go get yours.
