Probably not. Two seasons ago, was the best season of his Kawhi Leonard’s career by a significant margin. History tells us that if a player has a career season, they are likely to regress, at least a little.
However, Kawhi was only 25 that year and will be only 27 this season. He also is coming back from a pulled quad, not exactly the same as an Achilles. He is already warming to the idea of playing in Toronto and I think he will be motivated. He probably won’t be quite as good next season, but he should be close.
