There are very few players who age as Kevin Durant does. Despite being past the "prime years" relative to the average NBA player, he's still one of the best players in the entire NBA. He's the offensive go-to option for a Rockets team with championship aspirations, and that's saying something. 

Similar to LeBron James, Durant feels like a player we won't fully appreciate the longevity of until after he retires.

Who else in the NBA fits that mold?
