Listening to that rant, I don't get the impression that Jackson likes TP very much.
I get what he's saying though, and how it could taken wrongly (or rightly), but come on, Tony's injury WAS worse. His tendon ruptured and had to be surgically repaired. It is basically a worse version of Kawhi's injury. I don't mean people shouldn't read into TP's comments, just that he is medically correct. But his injury was surgically repaired, and there was a good chance that could have not worked out as well as it has. He's lucky he's still playing basketball at this high level.
Kawhi is trying to avoid surgery, and avoid putting his career in a surgeon's hands. I don't think there's anything wrong with that.
