Kawhi has always been one of the biggest "what ifs" in the history of NBA, of course there are a lot more as well and this isn't at the top for sure but he is a big one. This dude won 2 fmvp's and is not even considered remotely anywhere the top, not even in any top 10 topics ever, I am not saying that he is not in it, I am saying he is not even considered to be in it at all, ever.
How many other 2 time finals mvp's can you name that people wouldn't even consider a small slight chance of them being in top 10? Nobody. That dude spent 2 years as bringing championship to his team, and all rest of his career as spending time resting his injury. That's really not normal and should be considered a bit weird but unlucky at the same time.
The king of "Load Management".
That's what some people call him right now, and that's true. Ever since he went to the Clippers after winning a title with the Raptors, he's been doing this load management sh*t that ruins the whole team. What's worse is that, he only says that he will not play just minutes or hours before the game even starts. I mean like WTF!!. You're being paid, and you will choose whether you will play or not even though you can play?
Anyway with regards to him being considered in the top 10, he's easily on the top 10 on the list of current active players right now "IF" he's healthy. We already saw how good he is back when he was in the Raptors, and he won a title there. I mean with his skills on both offense, and defense, I can put him in the top 10 conversation no doubts. It's just that injuries really ruin one's career, and that includes him. We know his potential, and how good he is.
2 Finals MVP's don't matter if you play like that. Always getting injured, can't be a leader, always silent, and at the same time,
don't know how to laugh 
. Kidding aside, Kawhi no doubt is a top 10 player, and there was a time where even Lebron is afraid of him when Kawhi is in the court because of how good he is defensively. I already said the problem with him, and I hope there will be a cure with that one.
