This is Leonard in his prime and guess what? he is better than before. when he leads his team to championship without the help of his past teammates. Wherever he may go, he is making his current team compete to the championship and that's what I like about Leonard. the most humble NBA player I have ever seen.
I think Leonard is on his prime when he gave a championship to the Raptors, with the Spurs I can't tell if he is their best player but I guess he is since he won a Finals MVP award and got his firt championship at the young age of 22 years old. He has a different role now with the Clippers as people are already expecting he can carry the team unlike with the Spurs where the big 3 is still active that time.
