The good thing about KD and Klay is that they are not late in their careers right now, they are still pretty young compared to some of the other big injuries like theirs and that is why there is a chance they can find a way to recover with time
In a way, Kahwi made a good example of how serious injuries should be treated. They should follow his advise, "come back when you feel healthy". Kahwi has been ridiculed before and look where he is now after taking full time to recover.
Right advice for the superstars but they have their ego and has a choice not to listen. However, the finals has ended and there's more time for them to rest and recover.
The injuries of these superstars will soon regain back their health and ready to take off for the upcoming season.
The time frame for resting will be depending to how players wanted to be fully recovered since Kawhi chooses to take more time and rest for its benefits he get what he wanted and prove it worth, now he came back with full strength and bring his team a title.
For those who are still in their injuries, they can choose between playing quickly or fast recoveries or rest till the time that the conditions of their body allow them to play back with full chemistry.
