24.    Kawhi Leonard-23.46

LA Clippers superstar Kawhi Leonard is among the best players in the NBA today, though he initially got his start with the San Antonio Spurs as a defensive specialist. San Antonio expected him to be a 3 and D type of wing but he quickly exceeded expectations and eventually emerged as a superstar. 

He helped the Spurs win a championship in 2014, set a franchise record for wins in 2015-16 and reach the Conference Finals in 2016-17. Despite that, he fell out with the Spurs, and he demanded to be traded. He was then dealt to the Toronto Raptors, where he led them to their best season in franchise history and their first and only championship.

Leonard has struggled with injuries throughout his career and it's unlikely that he will have the same longevity that other superstars on this list have had. Although he is unlikely to play even 900 games over the course of his career, his peak is higher than most.

Few players can say that they have two Defensive Player of the Year awards as well as two Finals MVPs for two different teams. Overall, Leonard's ranking inside the top 25 in PER appears to be spot on when compared to his all-time ranking.
