More to it than Kawhi being a “quitter”.
I don’t blame Leonard for not playing if he doesn’t feel right. He knows his body better than Spurs medical staff. They work for the Spurs, not Leonard. Celtics medical staff thought it was ok for Isaiah to play more than 1/3 of season on a bad hip and it cost him at minimum $100 million in future earnings. Leonard needs to look out for himself as he has a well earned super max extension coming up. Teams show no loyalty to players, so when a superstar(and Kawhi is a superstar) has leverage over a team, he should use it. This is a business for both sides.
