Those four players belong to the best players of the 2010‘s. All of them won the MVP award. They are the same age (born 1988-1989).
But only Durant & Curry still are among the best players in the league. Why did they decline so much less than Harden and Westbrook?
Westbrook relied a lot on his athleticism and was never the best jump shooter (with exception to that pull-up middy that he now tends to back rim)
Like AI, Harden’s affinity for partying it up has aged him/ affected his conditioning, especially after the hammy in 2021
