Kawhi would be in Top 20 all-time with another win, maybe Top-15. He might be Top-20 now, but for me at least, he needs to sustain that level over a longer period of time. Another 3-5 years and one more championship to get into the Top-10.
If you’re talking 1-3, then absolutely not. He’s had amazing talent and coaching around him for most of his career, and he hasn’t done it for a sustained period yet. Most of the guys ahead of him were elite for over a decade, Kawhi has only been elite for 3-5 years.
